A question about Accordion in Muse on positioning

A question about Accordion in Muse - e.g. I put an Accordion a web page with an anchor position and use a menu button to point to the location. However, when I resize the browser such that it is narrower than before, the Accordion actually moves towards the left side when I use the menu button to go to the Accordion. I don't want this, in fact, I would like the Accordion maintains a certain distance from the left of the browser's edge, instead of from the right. Could you please help?
Perhaps I am not decsribAn example is from the Site of the day: http://corlessmason.com/#portfolio, when I resize the browser narrower, the panel of pictures maintains its position and it's only being cropped off, instead of being pushed towards the left - that's pretty much I would like to achieve.
Thank you.

actually I found the solution:
Muse Vertical Website Shift
it works perfectly now!

Some questions about Muse

First of all, I would like to say that I am very impressed with how well Muse works and how easy it was to create a website that satisfies me. Before I started a daily updated website I thought I would encounter many problems I will not be able to solve. I have only had a few minor issues which I would like to share with you.
The most problems I have with a horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html). Marking and copying of a text is possible only on the last (top) layer of a document. The same situation is with widgets or anything connected with rollover state - it does not work. In the above example it would be perfect to use a composition/tooltip widget on the first page. Unfortunately, you cannot even move the cursor into it.
It would be helpful to have an option of rolling a mouse to an anchor (like in here http://www.play.pl/super-smartfony/lg-nexus-5.html and here http://www.thepetedesign.com/demos/onepage_scroll_demo.html). I mean any action of a mouse wheel would make a move to another anchor/screen. It would make navigation of my site very easy.
Is it possible to create a widget with a function next anchor/previous anchor? Currently, in the menu every button must be connected to a different anchor for the menu to be functional.
A question about Adobe Muse. Is it possible to create panels in different columns? It would make it easier to go through all the sophisticated program functions.
The hits from Facebook have sometimes very long links, eg.
(http://www.leftlane.pl/sty14/mclaren-p1-nowy-krol-nurburgring.html?fb_action_ids=143235557 3667782&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582). If such a link is activated, the anchors in the menu do not work on any page. I mean the backlight of an active state, which helps the user to find out where on page they currently are. The problem also occurs when in the name of a html file polish fonts exist. And sometimes the dots does not work without any reason, mostly in the main page, sometimes in the cooperation page either (http://www.leftlane.pl/wspolpraca/). In the first case (on main page), I do not know why. I have checked if they did not drop into a state button by accident, moved them among the layers, numbered them from scratch and it did not help. In the cooperation page, the first anchor does not work if it is in Y axle set at 0. If I move it right direction- everything is ok.
The text frame with background fill does not change text color in overlay state (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html). I mean a source button at the beginning of every text. I would like a dark text and a light layer in a rollover, but the text after export and moving cursor into it does not change color for some reason.
I was not sure whether to keep everything (whole website) in one Muse file (but I may be mistaken?). I have decided to divide it into months. Everyone is in a different Muse file. If something goes wrong, I will not have any trouble with an upload of a whole site, which is going to get bigger and bigger.
The problem is that every file has two master pages. Everything works well up to the moment when I realize how many times I have to make changes in upper menu when I need to add something there. I have already 5 files, every with 2 masters. Is there any way to solve this problem? Maybe something to do with Business Catalyst, where I could connect a menu to every subpage independently, deleting it from Muse file? Doing so I would be able to edit it everywhere from one place. It would make my work much easier, but I have no idea jendak how to do it.
The comments Disqus do not load, especially at horizontal layouts (http://www.leftlane.pl/sty14/2014-infiniti-q50-eau-rouge-concept.html). I have exchanged some mails and screenshots with Disqus help. I have sent them a screenshot where the comments are not loaded, because they almost never load. They have replied that it works at their place even with attached screenshot. I have a hard time to discuss it, because it does not work with me and with my friends either. Maybe you could fix it? I would not like to end up with awful facebook comments ;). The problem is with Firefox on PC and Mac. Chrome, Safari and Opera work ok.
YouTube movie level layouts do not work well with IE11 and Safari 7 (http://www.leftlane.pl/sty14/wypadki-drogowe--004.html). The background should roll left, but in the above mentioned browsers it jumps up. Moreover the scrolling with menu dots is not fluent on Firefox, but I guess it is due to Firefox issues? The same layout but in vertical version rolls fluently in Firefox (http://www.leftlane.pl/sty14/polskie-wypadki--005.html).
Now, viewing the website on new smartphones and tablets. I know it is not a mobile/tablet layout, but I tried to make it possible to be used on mobile hardware with HD (1280) display. I mean most of all horizontal layouts (http://www.leftlane.pl/sty14/2015-hyundai-genesis.html), where If we want to roll left, we need to roll down. Is there a way to make it possible to move the finger the direction in which the layout goes?
On Android phones (Nexus 4, Android 4.4.2, Chrome 32) the fade away background effect does not work, although I have spent a lot of time over it (http://www.leftlane.pl/lut14/koniec-produkcji-elektrycznego-renault-fluence-ze!.html). It is ok on PC, but on the phone it does not look good. A whole picture moves from a lower layer instead of an edge which spoils everything.
This layout does not look good on Android (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html#a07). The background does not fill the whole width of a page. There are also problems with a photo gallery, where full screen pictures should fill more of a screen.
Is it possible to make an option of scroll effects/motions for a fullscreen slideshow widget thumbnails (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06)? It would help me with designing layouts. Currently, it can go from a bottom of a page at x1 speed or emerge (like in this layout) by changing opacity. Something more will be needed, I suppose.
Sometimes the pictures from gallery (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06 download very slowly. The website is hosted at Business Catalyst. I cannot state when exactly it happens, most of the time it works ok.
I really like layouts like this (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a03). On the top is a description and a main text, and the picture is a filled object with a hold set at the bottom edge. That is why there is a nice effect of a filling a whole screen- nevertheless the resolution that is set. It works perfect on PC, but on Android the picture goes beyond the screen. You can do something about it?
In horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html) holding of a filling object does not work. Everything is always held to upper edge of a screen regardless the settings. Possibility of holding the picture to the bottom edge or center would make my work much easier.
According to UE regulations we have to inform about the cookies. I do not know how to do it in Muse. I mean, when the message shows up one time and is accepted, there would be no need to show it again and again during another visit on the website. Is there any way to do it? Is there any widget for it maybe?
The YouTube widget sometimes changes size just like that. It is so when the miniature of the movie does not load, and the widget is set to stroke (in our case 4 pixels, rounded to 1 pixel). As I remember ( in case of a load error) it extends for 8 pixels wide.
Last but not least - we use the cheapest hosting plan in Business Catalyst. The monthly bandwidth is enough, although we have a lot of pictures and we worried about it at first. Yet we are running out of the disk storage very quickly. We have used more than a half of a 1 GB after a month. We do not want to change BC for a different one, because we like the way it is connected with Muse. But we do not want to buy the most expensive package - but only this one has more disk space. We do not need any other of these functions and it would devastate our budget. Do we have any other option?
I’m using Adobe Muse 7.2 on OS X 10.9.1.
and I'm sending Muse file to <[email protected]>

Unfortunatley, there is no way to get a code view in Muse. I know quite a few people requested it in the previous forum, but not really sure where that ended up. Also, you may not want to bring the html into DW unless you only have 1 or 2 small changes 2 make. Two reasons. First, it isnt backwards compatible, so if you are planning on updating that site in Muse, you will need to make those changes in DW everytime you update. Second, by all accounts the HTML that Muse puts out is not pretty or easy to work with. Unlike you, I am code averse, but there was a lenghty discussion on the previous forum on this topic. I know they were striving to make it better with every release, just not sure where it is at this point.
Dont think I am reading that second question right, but there was a ton of info on that old site. You may want to take a look there, people posted a ton of great unique solutions, so it worth a look.
Here is the link to the old forums- http://support.muse.adobe.com/muse

Questions about Adobe Muse CC single-app membership.

When speaking to adobe customer service reps about Adobe Muse I feel like their taking me around in circles. My annual membership to the current Adobe Muse is going to expire in June. So before I sign on for another year I had some basic questions that seem to be baffling the adobe reps. one rep called Travis just hung up on me.
My questions;
With an Adobe Muse CC single-app membership.
Can I host a site on Business Catalyst for free?
The rep said I have to purchase Business Catalyst separately from Adobe Muse
This adobe page says, “An Adobe Muse CC one-year single-app membership includes hosting for one webBasics site
(http://www.adobe.com/au/products/muse/faq.edu.html)
How much space do I get on www.creativecloud.comwith a single-app membership?
The rep said I get 20GB when Adobe Muse becomes Adobe Muse CC in June
I currently have Adobe Muse and I have 20GB of space on creative cloud.
This adobe page says I get 10 GB (http://www.adobe.com/au/products/muse/faq.edu.html)
This adobe page says I get 20 GB (http://www.adobe.com/au/products/muse/features.edu.html)
Can someone pleas answer these questions!

With an Adobe Muse subscription, you get BC website hosting for 1 webBasics site. With a subscription to the creative cloud, hosting for 5 webBasics sites are included.
Single app subscriptions get 20GB of storage space on creative cloud.
I'll try to get that first link updated with the correct info.

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!

Questions about using a PDF form online

I have a client who wants to create an online version of a PDF form that they are currently using. I am currently trying to explain to them that this would be best done as an HTML web form, but I may not win this argument. I have only used PDFs for printed forms (either hand-written or using form fields) so I am not familiar with any problems that converting the form for use online would entail.
When the 'Submit' button is pressed on the form, is there a way to redirect to another web page after the data is submitted? (i.e. does the PDF have access to it's outer 'environment'?)
Are there any security issues submitting data using the PDF form as opposed to using a standard web form? (There may be sensitive data being submitted)
I'm not sure how they plan to handle the data that is submitted, but there are several options in the submitForm parameters - I am assuming that using the HTML option would submit the data in the same format as a web form would. Am I correct here?
Can the PDF be prevented from being downloaded or printed? This form should only be used to submit data to their server, not as a printed form.
Are there any other 'gotchas' that I need to look out for? Does anyone have a recommendation for a site which contains any tutorials or guidelines for using PDF forms online?

Thanks for the information.
Yes, I agree that there is less reason for it to be a PDF form (Actually, no real reason other than the original form already exists in PDF), but I am unfortunately in the position that my input in this project is not necessarily being considered (my company is following direct -and inconsistent- directions from the client, and I have no contact with the client to ask questions about what their actual needs are). I have been told to give the client the 'Tomato' that they are asking for, even though they are describing an 'Apple'.
The reason this form is not meant to be printed is that we have replaced the 'Signature' fields from the original form with checkboxes that the user must check to confirm they have 'signed' the document. If they are to print/fax/whatever the document, they should use the original form, not this one. And I am still trying to explain to them that this would be better served with an HTML web form, but I fear I am losing that battle.
I have brought up the fact that it is not 100% guaranteed that Acrobat will be available in the browser, although I can only guess that it is less than likely that anyone will not have some sort of PDF viewer available to their browser.
I will also mention that issues may arise if the file is not submitted from within the browser.

Question about lead in music for podcasting.

Question about lead in music for podcasting.
I listen to many other podcasts and there are those which play lead in music with bit of music inside their podcast. The music are songs we all know and enjoy. I have notice that they only play short small clips of these songs and are not royalty free songs.
My Question would be is there a limit of time which you can play any song with out paying for it and use it in a podcast legally.
Thanks Mike

Legally you cannot use copyright music without written permission or a licence from a recognized authority, no matter how short the clip. Many people do this and get away with it (and for full tracks too) and it's debatable how much notice anyone is likely to take, or whether they would be bothered about a short clip. But the legal position is, it's not legal.

Question.
I look for integrated in the legend bloc of diaporama, a widget such as "Accordion" for, with a click, or passing with mouse, open a new legend for each photo. I tried with "Accordion" of Muse, it does not work. I tried copy/paste, mais no result. The widget disappear in bloc legend. disparaître. Have you one solution?
Thank you,
Loïc

Accordion or Tabbed panel should to it, with click and open container.
Please provide site url where this does not work, also if you can provide an example where we can see the exact action then it would help us.
Thanks,

Basic questions about Infocube

Hi, everyone.
I got very basic questions about infocube data handling.
With infopackage, I extracted all the data about employees from R/3.
But there were some mistakes during inputting employee data, like positions,
so I just extracted those employees data once more.
Now I have two requests in infocube, where the first one has some wrong data.
Is there any solutions about this?
I might got it all wrong, so as beginner, any suggestions and explanations will
be grateful.

Hi,
You can manually delete the earlier request by going in the Manage option of the cube. select the request and click on delete icon at the bottom.
Other option is to make setting in the Infopackage to delete similar or overlapping request.
Data target tab --> 6th column Automatic loading / deletion of similar request. --> click on the blank icon --> you will get a pop-up --> select the radio button - "delete existing request" --> Select Conditions --> Infosource are same, datasource are same and source system are same, --> selections are "Same or More Comprehensive "
Assign points if useful
Regards
Venkata Devaraj !!!

Question about Java Errors

I have some questions about some java errors
1. what kind of errors are contained in Error class?
2.does this class contain only runtime errors?
3. if the question number 2 is positive, what about InstantiationError which is a compile error and is a subclass of Error.
4.When our program is out of memory, which processes are done for an error to be produced. is the error actually from OS or VM?

I have some questions about some java errors
1. what kind of errors are contained in Error class?An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch.
2.does this class contain only runtime errors?No
3. if the question number 2 is positive, what about
InstantiationError which is a compile error and is a
subclass of Error.
4.When our program is out of memory, which processes
are done for an error to be produced. is the error
actually from OS or VM?Various - both, depending on where the error occurred.

Question about "Native ISO" and Color Grading in PP

I have a question about "Native ISO" in the real world and how it relates to color grading. I was shooting 35mm film before all these digital cameras became flat-out amazing practically overnight. Then the goal was always to shoot with the lowest ISO possible to achieve the least amount of grain (unless you were making an artistic decision to get that look). If I was shooting outside plus had a nice lighting package I'd shoot 5201/50 ASA (Daylight) and 5212/100 ASA (Tungsten) 99 times out of 100.
I've recently been shooting a lot with the Blackmagic 4K and have read that its "Native ISO" is 400. Because of my film background this seems counter-intuitive. Yesterday I was shooting for a client and had the camera at an f16 with a 200 ISO. Because of what I'd read, I was tempted stop down to an f22 and change my ISO to 400... but the "little film voice in my head" just wouldn't let me do it. It kept telling me "Higher ISO means more noise... stay at 200 and you will get a cleaner image".
So how does it work with "Native ISO"? Should I really shoot at a 400 ISO every chance I get in order to capture the best image for how the camera is calibrated? Will it really give me more latitude when color grading? Or would I still get a cleaner image staying at ISO 200? I've Googled around quite, but haven't found any articles that answer specifically this question. Would love to hear from someone who knows a bit more on the subject or has a link that could point me in the right direction.
Thanks much.

Hey, shooter ... yea, interesting discussion and always nice to learn. Great pic, too!
jamesp2 ...
Great answer. I've followed quite a bit of the discussion about the BM cams as well, one does feel a need to check out the possibilities for that next beastie one will need to acquire. But ... which one?
I've always been a bit of a hard-case about testing testing testing. For instance, what happens with dome down or use of a flat diffuser vs. dome in the up position in metering? Back in the film days, we had our own lab and did our own printing as well as the um ... difficult images ... from other studios. I needed to know how to get exactly the same diffuse highlight no matter whether it was a "standard" light 3:1 studio shot, or a near-profile with no fill that needs dark shadows. I tested & burned through boxes of medium-format polaroid & 120 film and a lot of color paper. Finding? To get the same print time no matter the contrast or lighting style, needed to be metered either with the flat disc (Minolta) or dome-down (Sekonic) and held at the highlight-location pointed at the main light source. I could meter and nail the exposure every time. Ahh no, insist so many ... one must have the dome on/up and pointed at the camera! Right. Do that, change the contrast, and see what happens to your diffuse forehead highlight on a densitometer ... and see how your printing exposure times change. Oh, and you've just moved your center-of-exposure up or down on the film's H&D curve, which will also change the way the shadows & highlights print. In truth, though it was subtle, we had realistically no matter latitude for a best-case image with pro neg film as one had with chromes. You could probably get away with being "off" easier, but it still wasn't dead-on.
So wading into video ... oi vey, you may have noticed the things claimed here there & everywhere ... this setting is God's Gift to Humanity but no, it's total crap ... this sensor is totally flawed but someone else is certain it's the finest piece out there. Yes, opinions will be all over ... but ... in film, it was the densitometer. In video, it's the scopes. Truth. And getting to that can be a right pain. I've seen quite a few contradictory comments about using the BM cams in film mode and also at ISO 200. Yours above gives the most ... comforting? ... explanation (for me) because of your reference to your scopes & the waveform patterns. Thank you.
Love to learn ...

I have many questions about this program, but let me ask this one first:
In the TrueFalseQeustion class, why are there so many constructors? What is the purpose of setting some of the variables to default values?
Thank you very much!!!

Stop ignoring the error messages. You seem to think that an error message means you're doing the assignment wrong. It's probably a simple fix. Post the exact error messages, as well as the code that corresponds to them. The error message will tell you exactly what line the problem occurs on, so you know right where to look.Hi,

} I don't understand why the assignment wants me to build a method in the MultpleChoiceQuestion class to store the potential answer choices, I can make the program display the potential answer choices by including them in the questionText as following in the QuizDriver class
Question x;
x = new MultipleChoiceQuestion("What is the color of the car\na.Red\nb.Green", "a. Red", 3);
t.addQuestion(x); I don't know how to allow the client to construct the list of answer choices one at a time(add one potential answer choice by calling the addAsnwerChoices() method once)
Here are a few original sentences of my assignment which describe what I should do with the MultipleChoiceQuestion class
Using TrueFalseQuestion as a model, develop a new MultipleChoiceQuestion class that can be used to represent a problem where the user must select one of several answer choices (e.g., "Select answer (a), (b), (c), or (d)."). This new question type should have all of the same externally-visible functionality as TrueFalseQuestion, except that it must:
maintain a list of potential answer choices
provide a method that allows the client to construct the list of answer choices one at a time (i.e., the client should be able to call an addAnswerChoice() method to pass a new answer option to the MultipleChoiceQuestion.)
display (as part of the question text) the list of answer choices with appropriate letters ("abcd" instead of "0123") I don't understand what these sentences mean.
1. "Maintain a list of potential answer choices"-- this reminds me of the getPossibleAnswerChoice() method in the TrueFalseQuestion class
public String[] getPossibleAnswerChoice ()
        String[] possibleAnswerChoice = {"true", "false"};
        return possibleAnswerChoice;
    }I wonder that if the potential answer choices I have to store in the MultipleChoiceQuestion class are only letters "a", "b", "c", "d", etc, or include the answer text coming after the letters(eg. a.Red, b.Green)
2. "provide a method that allows the client to construct the list of answer choices one at a time". How do I achieve the functionality "one at a time"? Do I need to pass the input of the client (a potential answer choice) to the variable of the method which stores the list of potential answers?
3. "display (as part of the question text) the list of answer choices with appropriate letters". My question here is that: When the client type in one possible answer, should I append it to the variable questionText? (So I use the questionText variable in the methods of the first and second steps)
Thank you very much for your nice help!

Some question about fade in // fade out by hideEffect and showEffect in Actionscript

Some question about fade in // fade out by hideEffect and
showEffect in Actionscript
Please kindly take a look at the following page:
http://camusmiu.no-ip.com/HounganQuestion/PictureHolderTest.html
(can view source)
I tried to make an image preloaded and scale the image to
it's preferred size.
When I came to consolidate the stuff into a component, I
found the application goes weird as I implementation the show/hide
effect.
The third trial which just hide and show the images directly,
instead of using viewstack, fail to bring the second image onto
screen.
It just used fadeOut instead of fadeIn(you see there is a
flash of the second image)
After some study of showEffect and hideEffect behaviour,
seems the mechanism of hide/show a component works in this way:
this._fadeIn:Fade = new Fade();
this._fadeIn.alphaFrom = 0;
this._fadeIn.alphaTo = 1;
this._fadeIn.duration = 1000;
this._fadeOut:Fade = new Fade();
this._fadeOut.alphaFrom = 1;
this._fadeOut.alphaTo = 0;
this._fadeOut.duration = 1000;
Component_A.visible = true;
Component_A.setStyle("showEffect", this._fadeIn);
Component_A.setStyle("hideEffect", this._fadeOut);
then when I set Component_A.visible = false, the sequence
works like following:
Component_A.visible = true
Component_A.visible = true, alpha = 100;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 0;
Component_A.visible = false;
The above sequence works visa versa as:
Component_A.visible = false;
Component_A.visible = true, alpha = 0;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 100;
Component_A.visible = true;
(Correct me if i am wrong)
========================================================================================== ====
From what I observe from the application, I have two
question.
1) When more than one component using the this._fadeIn,
this_fadeOut as the hide/show effects, the component in instance of
this._fadeIn? will it mess out if more than one component using the
fadeIn instance in the same time?
2) from the third component, i.e. PictureHolder3, when I load
other the picture , it fade out the new image instead of fading
in... Seems there is problem if I hide show too frequent. I think
when I hide then show right the way, the component only do the hide
part...
Can someone pls look into it and tell me what I did wrong?
Cuz in normal practice I don't think appropriate to use ViewStack
in Actionscript...

Question about get web service result in actionscript and convert data format

Hi, All
I have question about how to get dataset from web services
and put it in tree structure. I have 2 questions about this:
1, How can I get data correctly in actionscript?
I have no problem to get data by
<mx:ArrayCollection id="acFolder"
source="{mx.utils.ArrayUtil.toArray(MyGServices.getFolder.lastResult)}"
/>
And display in datagrid.
But when I try to use
public function
handleFolderContents(event:mx.rpc.events.ResultEvent):void{
arData=mx.utils.ArrayUtil.toArray(event.result);
acData=new ArrayCollection(arData);
input.text=acData.getItemAt(0).id;
Seems I can’t get data, it always say:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
2, how to convert data format
I get data from web service and want to convert it to tree
structure, as mention below:
I get:
<Array>
<id>111</id>
<Name>Production1</Name>
</Array>
<Array>
<id>222</id>
<Name>Production2</Name>
</Array>
Convert to:
<mx:XMLList id="treeData">
<node>
<node label="Production1" data="111">
<node label="Production2" data="222"/>
</node>
</node>
</mx:XMLList>
Please help me.
Thanks.

First, don't specify the package path in the argument
declaration. Instead import the event object:
import mx.rpc.events.ResultEvent;
The docs state this emphatically.
Second, try "lastResult", in place of "result":
arData=mx.utils.ArrayUtil.toArray(event.lastResult); // I am
not positive about this. I maybe recall reading that result was ok
for the event object, but maybe not.
Finally, why do you want to convert the xml? You certainly
could, but it would be a manual process, recursively reading the
existing xml nodes and building the new structure, but again, why?
Just use a labelFunction if necessary to display the nodes as
you wish.

Question about Page Builder behavior - how to get a "please wait message" ?

Hi all together,
I got a question about Portal Framework / Page Buider handling iView Integration.
We are working with a lot of App Integrator iViews and often the pages includes with app integrator are loading longer than the rest of the portal. So there is the idea to put in a "please wait while loading message" for the enduser.
I analysed the html code, the page builder is generating and foud out 3 diffrent approaches how the page buider is rendering the IFRAME with the integrated application configured with an app integrator iView.
My question is how can I influence this behavior to put a "please wait while loading message"?
Different types of iView integration in the client I have seen:
a) direct loading of the content in the IFRAME (<iframe id="" ... scr="/mysource">)
b) Filling the iframe with 'about:blank' and loading the content later by filling a form with JS
( <iframe id="" .... scr="about:blank">and after the iframe <form id="" action="mysource" ...>
c) Filling the iframe with a html file from the portal layout and loading the content later by filling a form with JS (similar to b)
( <iframe id=""" ....scr="/irj/portalapps/com.sap.test.mylayout/html/blank.html>
I checked that variant b) is getting generated when loading a page with different components on the side (not only the app integrator iview) and variant c) is generated when just one app integrator iView is positioned (no portal page).
Goal: To get the "please wait picture" I want to know how to get variant c) in cases of different elements on one page
So I would be able to put this picture on the HTML-Page in the Portal layout (blank.html)
Hope, someone with a deep portal / page builder know-how can help me out!
Another way: Does anybody knows another way how to put a "please wait message" while app integrator application is not loaded yet?
Thanks in Advance and kind regards,
Jens

Hi Jens,
there are several reasons why you don't get the loading animation:
Web Dynpro ABAP: https://service.sap.com/sap/support/notes/1432358 -> missing configuration
Wrong height size for iView: https://service.sap.com/sap/support/notes/1358494 -> alter configuration of the iFrame height (loading animation gets displayed, but is hidden)
FPN, BSP, BEx: https://service.sap.com/sap/support/notes/1290995 -> AI isn't showing the animation because of performance considerations. I guess that is your case. Depending on your portal version this is a simple service configuration or involves some customization.

Tobias

Question about strange cursor behavior - Sybase ASE 12.5.4

Hi folks,
I have a stored procedure in Sybase ASE 12.5.4 presenting a strange behavior. Follow below some code to simulate the error.
/* Create the table structure */
drop table tbx1
go
create table tbx1
(c1 int,
c2 int,
c3 char)
go
/* Create a CLUSTERED index NOT UNIQUE */
create clustered index idx1 on tbx1 (c1)
go
/* Populate the table with few records */
insert into tbx1 select 1, 1, 'N'
insert into tbx1 select 2, 1, 'N'
insert into tbx1 select 2, 2, 'N'
go
/* Test case #1 - The following code will not fetch the 3rd record */
declare c1 cursor for
select c1, c2 from tbx1 where c3 = 'N'
go
declare @c1 int, @c2 int
open c1
fetch c1 into @c1, @c2
while @@sqlstatus = 0
begin
select @c1, @c2 -- View the current fetched row
update tbx1 set c3 = 'N' where c1 = @c1 and c2 = @c2
fetch c1 into @c1, @c2
end
close c1
deallocate cursor c1
/* Recreate the table structure */
drop table tbx1
go
create table tbx1
(c1 int,
c2 int,
c3 char)
go
create clustered index idx1 on tbx1 (c1)
go
/* Repopulate the table */
insert into tbx1 select 1, 1, 'N'
insert into tbx1 select 2, 1, 'N'
insert into tbx1 select 2, 2, 'N'
go
/* Test case #2 - The following code enters in an infinite loop, fetching the 3rd record indefinitely */
declare c1 cursor for
select c1, c2 from tbx1 where c3 = 'N'
go
declare @c1 int, @c2 int
open c1
fetch c1 into @c1, @c2
while @@sqlstatus = 0
begin
select @c1, @c2 -- View the current fetched row
update tbx1 set c3 = 'N' where c1 = @c1
fetch c1 into @c1, @c2
end
close c1
deallocate cursor c1
If we execute a select on tbx1 before execute Test case #1, the result is:
c1   c2    c3
1    1     N
2    1     N
2    2     N
If we execute the same select on tbx1 after execute Test case #1, the result is:
c1   c2    c3
1    1     N
2    2     N   --> row position changed
2    1     N   --> row position changed
Analyzing the execution plan, updates on both Test cases are being done in deferred mode.
Could someone answer my questions, please:
1 - After executing Test case #1, 2nd and 3rd record change this position in table. How could this happening since I'm not updating any fields in the clustered index? This have any relation with deferred update deleting and reinserting the rows on overflows pages?
2 - Suppose the updates are changing the rows position in the table, how could explain the inconsistent fetch order on cursor processing (on Test Case #1, only 2 records are fetched - on Test Case #2, the loop never ends)?
Regards,
Douglas

Thanks for your replies. I've already solved my problem, just creating a unique clustered index. But I haven't understood what happened yet in the 2 cases above.
As suggested by Mark, I've read Chapter 18 from Transact SQL Users Guide. In section
"Join cursor processing and data modifications", there is a citation about what happens with cursor position after a update:
"A searched or positioned update on an allpages-locked table can change the location of the row; for example, if it updates key columns of a clustered index. The cursor does not track the row; it remains positioned just before the next row at the original location. Positioned updates are not allowed until a subsequent fetch returns the next row. The updated row may be visible to the cursor a second time, if the row moves to a later position in the search order".
As stated above, the cursor position keeps the same independently if the rows change their order.
I don't know if my logic is very simplistic, but I imagine that what should happen in #Test Case 1 is (assuming the access method is a clustered index scan):
a) After the 2nd fetch, cursor position is on 2nd row:
c1   c2    c3
1    1     N
2    1     N   <-- cursor position
2    2     N
b) After the update, 2nd and 3rd rows switch their positions, but cursor should keep its position (before 3rd row):
c1   c2    c3
1    1     N
2    2     N
                <-- cursor position
2    1     N
c) On 3rd fetch, the 3rd row is read "again" and cursor reaches the end of table.
In relation #Test Case 2, I can't imagine how a cursor could enters a infinite loop since the cursor position shouldn't change and "apparently the row positions are the same" after the "incorrect" update.
Moreover, I still have doubts about how a field update that isn't in a clustered index can change row position in a allpages-locked table.
The main goal of my questions isn't solve the problems but get a better knowledge about some Sybase internals (and avoid similar problems in the future).
Please give me more detailed explanations about my questions and comment my analysis. Related readings about this issues are welcome.
