IView that displays different things depending on event

Hi list,
I need to create an iView that will be receiving different events from other iViews. This receiving iView will display different things depending on the event (eg. image maps, data sheet, etc). How should I implement this iView? Should this iView be multi-component and then the events triggers the correct component? Or should this iView be multi JSP pages with one component handling the event and calling the correct JSP page? Or are there any other suggestions/examples out there?
The image map is not simple either. It has several hotspots on one image map.
Thanks in Advance,
Jovanka

Display Different reports depending on values in a User Selectable Dropdown

Hello,
I want to create a report which has a Drop-down and depending on the value selected from the drop-down, i want to display different reports.
Say, a drop-down has 3 values, v1, v2 and v3. Now, if a user selects v1, he/she should see report r1. If v2 is selected, the user should see report r2. if v3 is selected from the drop-down, then report r3 should be visible. All the 3 reports have different structures (even different no. of columns). Also, v1, v2 and v3 are 3 different values belonging to a same picklist type field.
Do you think this is possible? If yes, How ?
Any sort of help will be highly appreciated. Thanks in advance.
Regards,
Ramil.

The only way i could see this working would be to create a picklist on a object and then create your three reports placing them within the same folder and name the report something under 30 charters then place the same name in the picklist value and create a weblink to the report which at selection of the report will run either report.

ICals on OS X & iOS display different time for same event

I am in UTC+8 time zone. My boss is in UTC-5 time zone. I have set up sync service on my MBA and iPhone iCals with my company's MS Exchange Server.
I have a weekly meeting invitation from my boss, my MBA iCal displays this meeting on 10:30pm which is wrong, while my iPhone and MS Server displays 9:30pm which is corret - the meeting takes places on 9:30pm my time.
All my other iCal events are fine on both devices, only this weekly event displays different time. I have taken with MBA and iPhone to travel around the world over the past half year and switched time zones on them, but they are all set to adjust time zones automatically, and they are with most up-to-date system. Why does MBA iCal displays wrong time? Can I adjust it? This problem exisits on Lion and now also on M Lion.
Thanks for everyone's attention and help in advance!

Try using floating time zones. It helped for me.

How can I add buttons that do different things to each row of an rpt result

Hi there,
I'm trying to figure out how to add buttons to each row of a report. Here is the scenario:
report query returns a set of data that needs to be "approved". The options are "Append", "Replace", or "Reject" (I want to make the results look like so:)
Person1 today blah, blah blah... Append button Replace button Reject button
Person2 today blah, blah, blah... Append button Replace button Reject button
PersonA today something, blah... Append button Replace button Reject button
and so on.
I'd like to set up the page so that there is an append, replace, reject button for each row returned by the report. So when the "Approver" clicks on the append button, something happens for that row, etc. How does one do this? So far I can only get the buttons to show up in the region. I also thought it might be possible to somehow turn the append, replace, reject text into links that called a plsql proceedure that would handle the action, but I'm not having any success with that idea either.
Edited by: user10361829 on Sep 29, 2009 12:10 PM

What I've done is make my report query as follows:
select field_a, field_b, field_c, 'Append', 'Replace', 'Reject'
from table_x
where field y = :PX_ID
That gives me the words (append, replace, reject) in the report. Then I go to the report attributes section and make a link out of the columns (append, replace, reject) so far, so good.
Next question is how to make clicking on those links activate an update action on tableN. In the column_link section there is a box marked "Request" that looks like it might be relevant because Request is a term connected to buttons, but I've no idea how to use it. Or, can one use the tabluar form element section of the report attributes page to connect the Append (pseudo column) to an action? I've looked at your example (Sam) with the delete button, but what I really need to see is the Apex menu that sets it up because there are so many levels in the interface it is not intuitive (at least for me). I know exactly what I want it to look like but I'm missing the crucial step to get there... Thanks for your help so far.
Column link section is described below :
Column Link     Top
Link Text      flashlight
     [*Append*][Icon 1][Icon 2][Icon 3][Icon 4][Icon 5]
Link Attributes
Target: *"Page in this application"*     Page: *10*
Reset Pagination
Request Clear Cache
Name     Value
Item 1      Px_page_item flashlight *#????#*          flashlight
Item 2      flashlight          flashlight
Item 3      flashlight          flashlight

Action that does different things based on width to height ratio

I have a few hunderd images I want to run a batch on and I am building the action I will use.
I need to do something I have not come accross before.
If the image is taller than wide I need to make the image 1024 pixels high.
else
If the image is wider than tall I need to make the image 1024 pixels wide.
How can I do something like this in an action?
Will I need to use a script instead?

Will File > Automate > Fit Image not suffice?
If not you may have to use a (different) Script as Actions alone (edit) basically don’t allow the user to set conditional operations.

IView Displaying Differently with Users

I have a transactional iView that displays a different screen view (GUI) for different users.
Is there a setting that needs to be changed or could it be something to do with the Users Authorisations?

Hi Sudha
Thanks for the reply.
I am logging on as both Users. The interesting thing is that one of the Users gets a pop up message when selecting the iView saying they have mail in their In Box. This is the one I'm having trouble with.
Once I have pressed the green tick to acknowledge the message and go into the iView it selects the Manager rather than a member of his staff in the iView.
When selecting a member of staff in the team viewer the entry does not appear in the iView.

PDF file displays different number of text blocks in Acrobat Pro CC 2014 and CS6 versions

Hi,
I've inherited a file at work that displays different numbers of text blocks, depending on the version of Acrobat Pro used to view the file. Here's the specific issue:
As viewed in CC 2014:
"Chapter 1 - Chapter One Title": Appears as two text blocks -- one for "Chapter 1 - " and one for "Chapter One Title"
As viewed in CS 6:
"Chapter 1 - Chapter One Title": Appears as a single text block -- "Chapter 1 - Chapter One Title"
This occurs only with regard to single-digit chapter numbers that are whole numbers. So:
Chapter 1, Chapter 5, and Chapter 7 entries appear as two blocks in CC 2014, one block in CS6.
Chapter 2.0, Chapter 6.1, Chapter 10, entries appear in single blocks in both CC 2014 and CS6.
The PDF file was created -- I believe -- through the save-to-PDF feature in Word 2010.
Any idea what's happening here?
Thanks.
David

First of all, there is no such thing as Acrobat CS6 or Acrobat CC 2014. We assume you are referring to Acrobat X and Acrobat XI respectively.
Secondly, how are you determining how many text blocks are in the PDF file? By use of the text touchup/edit function in Acrobat? If so, how this edit function displays text doesn't necessarily correspond to the actually underlying text fragments in the PDF file. In fact, sometimes it combines fragments based on heuristics. Those heuristics have varied with different version of Acrobat.
PDF as a file format doesn't know the context of the graphical objects such as text. There is no concept of a line, a sentence, a paragraph, a column, etc. in terms of text. Runs of text are context-insensitive. You will get “breaks” when switching between regular and italics or when unusual paragraph justification is involved.
Is the actual problem in trying to edit the text or something else?
If you post a file, and indicate what text we should look at, we can confirm what is actually going on in your file.

Displaying different content on Maximize of Portlet

Hi,
Is there a way by which i can display different content on Maximize event of a portlet than the one displayed in the normal portlet.
saw one <render:jspContentUri> taglib which promises to do that. but it only maximizes the existing content and does not change it.
Any help in this regard would be appreciated.
thanx in advance

Anyone know how to do this on a PageFlow portlet?

put a backing file on the portlet (backing files are just java classes

AbstractJSPBacking, see "backing file" property in IDE)
public boolean preRender(HttpServletRequest request, HttpServletResponse

PortletBackingContext pbc = PortletBackingContext.getPortletBackingContext(request);
WindowState ws = pbc.getWindowState();
if (ws.getName().equals("maximized"))
JspContentContext jcc JspContentContext getJspContentContext(request);
jcc.setContentUri("/mynew.jsp");
Note: you can put backing files on the Portlet and the JSpContent elements.
I'm
not sure if the IDE supports both of these. You may have to crack open
the .portlet
file and add the backing file to the JSPContent element.
<netuix:jspContent backingFile="comn.somecompany.yourBackingFile" contentUri="/portlets/myportlet.jsp"/>

How to display conditional things on the front panel ??

Hello,
What I am trying to do is this: The user will select some information from a combo box, and depending upon twhat he has selected I want to display different things based on his selection.
Any help will be appreciated.
Thanks,
Bira_pxi

You can programmatically change the visibility of any object using property nodes with the "visible?" property.
If the groups of elements are similarly arranged, use a tab indicator (place tab control...change to indicator) and place each group of FP elements on it's own tab. Now hide the tabs and select the active tab programmatically by writing the desired state to the tab indicator.
Another option is the use of subpanels.

Displaying different properties?

I have an iview which displays different users, and in the displayed properties for the Collection Render I have the following:
rnd:icon,rnd:displayname(contentLink)
This displays an icon and the username (with a link!).
What I want to do is display other properties e.g. Phone number, job description etc. Does anyone know the properties that need to be used or a list where I can find which ones can be used?
Thanks in advance!

Hi Phil,

With this, you'll see how to use the UME repository and how to map UME properties as KM properties (like: ume:department, ume:company etc).

BW Report iView that points to QueryView

I would like to have a BW Report iView that displays the standard icons (ie: Export to Excel, Create graph etc) and displays a BW Query View. My understanding is that this has to be a BW Report iView and not a BW Query iView because of single sign on will not work with the BW Query iView.
So appending the following to my URL works for QUERY but what works for QUERYVIEW?
CMD=LDOC&INFOCUBE=<CUBE>&QUERY=<QUERY NAME>
Thanks!

Yes SAP Portal can seamlessly integrate with CMS.

How to create a front panel display that lights up with different colours depending on its input signal?

I am doing a project where I have this array which has different voltage outputs for each grid. How do I create a front panel object that lights up with different colours depending on the voltage input or is there already such a pre-built function?
In addition, I wish to display these in an array on screen. Is there any pre-built function for this?

The simplest way would be an intensity graph. It gives you a 2D grid where each grid point is colored according to the value of a 2D array. The Z axis color ramp determines the color.
My second choice would be an array of colorboxes. (They could even be made to look like LEDs (see image, if course you can leave them square too), All you need is a scaling function thap maps voltages into a color ramp lookup table with an 8bit index)
(Using booleans and color property nodes is relatively clumsy. Booleans are meant for two states because the value is boolean. Since array elements can only differ in value, and not in properties, it will not even work. Color boxes have a color data type which is much more appropriate for this case)

How to make a form dynamic so that it displays different logos at runtime

I am working on some assignment wherein I would like to make a form dynamic so that in it's designated image holder it displays different logos/pictures at run time? First of all is there such a possibility?? I am still very new to this forum and also trying to understand the logic/bindings/heirarchy etc. in LCD. Any input would be highly appreciated.
Thanks in advance

LC 7 or 8 does not help load logs at runtime. However you can associate all your logs at design time and control their visibility property based on the events. This may help fulfill the requirements you have to an extent however adding number of images at design time will increase the size of the template.

Hi Karen,
The means that iTunes can no longer locate the songs (mp3/m4a) on the hard-drive and as such they won't even play in iTunes, let alone transfer to your iPod.
Have you recently re-organised your music folders? If you know where these songs are on your hard-drive then you could clear all of the tracks that display the symbol from iTunes and then add them again from their location either through the 'add folders to library' function or by dragging and dropping them diectly into iTunes from Windows Explorer.
