Using JavaScript & Dynamic Lists - ?? need help

Hello all! Sorry to post this under an unrelated topic (JSP & JSTL), but there wasn't a JavaScript forum.
Anyway, before I ask my questions...read the following:
You'll find the code for my example at the end of this post. Also, I've posted my code as html pages in here...but my original code was in the form of servlets.
Here's what I wanted to accomplish:
1) html page has a form with two select lists
2) select one option from the first select
3) javascript code takes care of populating the 2nd list with options stored in an array, based on the first selection made in the 1st list.
4) each <option>'s value is set to the page hello.html
Piece of cake! That all works, but here's the real issue:
Let's say you click on an option from the 1st <select> list, which populates the 2nd <select> list with some options. You then click on the 2nd box, select an option, and it jumps to hello.html.
Now you press the back button - here are some things I observed:
First, let me note, that for my example, I'm using car makes for the 1st list, and car models for the 2nd.
* notice that only the 1st select list is still showing the selection you made, but the 2nd one shows nothing. Plus, when you click on the 2nd list, all that is shown is, in my example, "Then a Model". Not the original options that populated this list, when you had selected a car make from the first.
*also, if you select "Then a Model" in the 2nd, it will error out, because there isn't a link set for that option. I would actually prefer that the page doesn't jump anywhere if "Then a Model" was to be selected. But I can probably fix that later.
* If you try to select the car make you had previously selected again in the 1st menu, it still shows the same thing in the 2nd. Not the car models that it showed you when you had first run the example.
*) You can get the model options for, just for example, "Acura" back into the 2nd, but you would have to select Audi or BMW and then select Acura again.
*) if you select the "Select a Make" option in the 1st, it doesn't display "Then a Model" in the second as I would like. But I can probably fix that later.
Now, here are my questions:
1) Does anybody know how I can keep the selections "selected" in the page, when a user comes back to it when they press the "back" button?
2) Do I have to store the options selected somewhere, so the page "remembers" what was selected?
3) Would it help if I used session tracking?
I was told that the problems I've described are because I've implemented a dynamic listbox.
The value is supposed to be lost if I move to the next page and then click back. Would any of you agree?
Any ideas/suggestions at all would be very much appreciated!

So what is wrong because servlet prints bad value [object]

Can I create a multi-selection list using a dynamic list of values?

I'm reading section 19.7.3 from the dev guide - it explains how to create a selectOneListbox using a dynamic list of values. Is it possible to create a multi-select listbox from a dynamic list of values?
What I would like to do - I have a read-only view object with a hard-coded query - I would like to display the results of the query in a dropdown list box, or dropdown list box with boolean checkboxes, to allow the user to select multiple items from the list. How can I accomplish this?
thanks

Hi JavaX,
I don't know of any JSF components (at least not any ADF Faces components) that lets you do multiple selection in a drop-down. There is an af:selectManyListbox, but it does not render as a drop-down.

Use the session variable from the log in method (MM_Username as I recall) to create a recordset that you then use in the dynamic list versus using the whole table.

Creating 2D List - Need Help

Hi all,
I need help with creating a "ragged" 2D array. The situation is that the columns have a static length which I know in advance but the number of rows needs to be defined per coloum seperatly. i know that i can create a ragged 2D array by setting the rows and looping throuh the rows setting the length (i.e. number of columns) but I have the opposite values. is this possible??

Number of rows per column? A 2d array is basically
one column with M rows and each row is N items wide.
So define one collection object, I'll use a List for
the sake of argument. This is that one column with M
rows. For each row, add a List as an element in this
column, and add N elements to this row List. There
you go, a variable column length and each row is of a
variable length as well.The issue i have is when defining the 2d array i.e. lets say of type int
int[][] array = new int[M][N]
I do not know M but do know the value of N. only after I have defined this section I can then continue to define M for each N .. any ideas?

Help! I have a Used Mac Book Pro need help with apps update

My ex bought me a mac book pro and purchased all of the apps and uploaded the apps under is apple id. I just recently update the new software now i can't get access to iPhoto, and other apps because its asking me for my password but his apple id coming up is there any way i re install these apps under my apple id. Please help I can used iPhoto.

You cannot use or upgrade anything that is registered with his Apple ID. You must re-purchase it all using your Apple ID and your iTunes account. This includes the operating system as well. Essentially, you erase the drive and start from scratch. Here's how to get started:
Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer. You can decide which apps you want to purchase (or download free) from the App Store where you will set up your own account and your own Apple ID if you don't have one.

I am unable to transfer my pictures from iphoto after editing back to my external hard disc. How do I do it. Previously I used Windows and this is the first time I am using a Macbook. Need help and tutorials.. Where can I find em..

Hi there, I am new to Apple Iphoto. I am having lots of problems in transferring my edited photos back to my external Hard disc after editing. How am I able to do it. will it be able to open in Windows OS... Previously I was using Windows and now i m new in using the Apple OS.. Need guidance.. Would really appreciate if any1 of u guys could help me through. are there any other applications that I could use to edit pictures.

Best if you try and explain what you are trying to acheive.
Iphoto is a different paradigm than you're used to. I don't understand why you are trying to transfer your edited photos back to an external disk.
There are tutorials here

Question about Dynamic Overclocking - Need help/advice

Hello,
I recently upgraded to version 3.9 bios on my MB (K8N SLI paltinum).
I had DOT enabled before the upgrade, on 9% extra. this worked ok. as soon as a program required heavy CPU, DOT kicked in and give me a 9% boost. and it also cooled off, back to normal operations when the CPU was idle again.
now, since the upgrade to 3.9, the DOT always stays at 9%? when booting up, when idling, always...? Is there a setting that I missed? or is it a bug in 3.9?
--> after the upgraded I loaded the optimized defaults.
thanx for any help.
S.

hi guys,
thnx all for the updates. I'm currently using DOT on 9%. It runs rock stable. IIf I set it on 11%, no problems.
C&Q is off, always was.
The problem with DOT is, that it doesn't do what it should do. (in 3.9 bios). nl, when the CPU runs on 0% load, no Over-clocking is need.
Any other settings that I should check?
Do I need to turn on Q&C?
thnx!

Use a dynamic list of email addresses to email a report via Business Objects Server 11

Post Author: wolfgang666
CA Forum: General
I use Business Objects Server version 11 to distribute reports via email but was asked if there was a way to only send the reports to those people listed in the report (which changes daily) instead of the entire distribution list. I can create a list of email addresses as a variable within the report but can't find any way to pass it to the Business Objects server "To:" field located in the destination screen. I would expect to see some option for sending to some value located in the report but alas no such option is evident. This seems like a feature the product should be capable of doing as it is so basic. Any other way to do this that anybody can think of? Any help is greatly appreciated. Thanks.
Matt Frazier

Hi Alan,
The simplest thing would be to simply use the Import Wizard to create a BIAR file and then back up the required CR's and instances to the BIAR file. So for instance you would use the "Import Folders and Objects" option. So the source system would be the system you are decomissioning and the Destination would be the BIAR file. Once that is done you can use the BIAR file to import the report content into another system in the future.

AA =94 - 100
BA =89 - 93
BB =84 - 88
CB =79 - 83

^but i couldn't solve my problem,i have to use double command and it says "required:int"This is telling you that what goes inside the parentheses in switch(...) must be an int. So you need to either supply an int value, or cast the value that you do supply.

Using own domain - newbie needs help!

I've never created a webpage before, so bear with me! I've started one in iWeb and purchased my own domain from GoDaddy.com. I changed the CNAME per the directions of iWeb/me.com. However, my page is not being published under the personal domain name I purchased. The domain name is showing up on me.com under my webpages. I've "Published All to .Mac" and when it asks me to go to my site after it's published, I get the generic GoDaddy parked site for my personal domain. What else do I need to do to get this working? Sorry to be so ignorant, but any help would be appreciated!
Thanks!!

What you need to do to set-up CNAME is to firstly enter your domain name into the personal domain name option of MobileMe. If you look, you will see that www is already there, so you don't need to enter this, just yourdomainname.com or whatever and then confirm it in the second box and click on done and it will be set.
You then need to go to your control panel settings at GoDaddy, where you got your domain name from. What you need is the DNS settings and your domain name should already show there. All are slightly different, but what you then need to do is enter www, then pick CNAME from a drop down menu or complete it and then either web.mac.com or web.me.com to redirect your domain name. This then means that you domain name will be forwarded to your iWeb site at web.mac.com.
If you want a simpler way to do it, you can just use web forwarding instead, which means that you don't need to complete the personal domain in your MobileMe account. All you need do is go to the web forwarding section of your control panel at GoDaddy and enter your domain name and then forward it to web.mac.com/username/sitename or web.me.com/username/sitename.
Remember that for CNAME forwarding you always forward to web.mac.com and for just forwarding you would enter web.mac.com/username/sitename.
CNAME forwarding can take up to 24 hours to take effect, so you could have a wait, although most hosting companies are a lot quicker than this.

JavaScript error. Need help!

Hi,
Since 2 weeks I encountered Javascript errors when starting Dreamweaver CS6.
1st one - While Executing onLoad in BusinessCatalyst.htm, the following JavaScript error(s) occured: In file "BusinessCatalyst": bcinit is not defined.
2nd one - The following JavaScript error(s) occured: At line 17 of file "C:\Program Files\Adobe\Adobe Dreamweaver CS6\Configuration\Shared\BC\JS\bc_ui_utils.js": MM.BC has no properties.
I don't know what this means and how to solve it. I've tried deleting the cache file and re-installing the software, but that didn't help. So can anyone guide me through the steps I need to take?
Thanks in advance!
Erik

Problem - Define Forms for Check Deposit List - Need Help

Hello Experts,
I want to extend the logic of T Code FP20 (Prog RFKKCK01),
Hence, I have created a 'Z' prog with the appropriate extension in the logic.
Now to take these change effectively, i have made corrensponding changes in the attached SAP Script (FKK_CHECKDEPOS) also.
Now, when I go to
Contract Accounts Receivable and Payable -> Business Transactions -> Payments -> Processing Incoming and Outgoing Payments ->Define Forms for Check Deposit List.
In this, I create a new Entry after removing the existing Entry of the same Company Code [1000     | ZRFKKCK01 | SapScript | ZFKK_CHECKDEPOS ]
it gives me an Error "Specify the key within the work area".
Specify the key within the work area
Message no. SV033
Diagnosis
You have attempted to create an entry whose key is not in the range defined for this area.
System Response
The entry cannot be created.
Procedure
Please check your entry.
Please Help me solving this problem.
Thanks!!

Thanks sbaranga. This code won't work for me.
<select>
<option value="P"if (statusIndicator.equals("Pending")){    selected}>
<option value="A"if (statusIndicator.equals("Approved")){    selected}>
</select>
In above code statusIndicator is ID I believe. I need to show selected item based on statusIndicator in database. Also it has to pass updated status to database incase if user changes status thru form.
If they select Pending then "P" will be passed to servlet and if they select Approved then it will pass "A" to servlet.
I will be receiving "A" or "P" from database when I am trying to retrive status value from database. Based on value "A" or "P" I need to change selected information on form.
Update and Retive form are same. this one form does everything display and update.
I hope this help to understand my question.
If you have any question then email me at [email protected]
Thank you.

ITunes .dll error. I can't use, uninstall, install iTunes - NEED HELP!

I can't even start up iTunes anymore. I get "iTunes has encountered a problem and needs to close. We are sorry for the inconvenience." I can get details on the error but it's all Greek to me. Any insights/thoughts? Your help would be most appreciated!
ibm t40 Windows XP Pro

If iTunes is crashing, why don't you send a crash log to those lazy Apple engineers.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log" If there's already a file there, it most likely has multiple crash logs in it (new crash logs are just appended to the end of the file). So, delete this file. This will make sure you're not sending extra information I don't need. These crash logs are text files, so you can open them in notepad or whatever to see what information you're sending.
So, get the machine setup to collect crash logs, do the thing that makes iTunes crash. You need to send that file to our buddy Roy. Make sure that you include:
(1) the drwtsn32.log file.
(2) the link to this thread.
(3) a one line description of your problem, i.e. "iTunes crashes on launch".
(4) the username that you're using here in the discussion boards.
Roy is getting a little swamped with messages and needs to make sure he gets all the information. And if he doesn't get that information, the message is just going to get dropped on the floor.
