Task-flow exception only cought first time

We're working on a larger scale application, that relies heavily on PL/SQL. Therefor we throw a lot of jboexceptions in our applciations. FK, UK and other validations throw an exception in the base, and are thrown as jboexceptions from the java level.
The problem is, that the exception is only shown for the user, once per in each running task flow. It looks alot like this issue: http://java.net/jira/browse/ADFEMG-18
The exception is vissibe in the log file.
I'm running JDeveloper 11.1.1.5.0
Is there a fix?

Hi,
the fix starts with you providing us more information about your error handling process.
Have you verified the problem to reproduce e.g in 11.1.1.6?
Does the problem reproduce in a test case ?
The EMG bug you reference says that the problem doesn't reproduce in 11.1.1.6, so the fix would be to upgrade to 11.1.1.6 if it is the same issue, or work through customer support to get a backport patch in case you cannot migrate

Need to restrict triggering of workflow only once(first time).

Hi guys,
I hv a requirement to trigger the workflow only once(first time).
whatever is the the condition/changes in document, it should not trigger for second time.
do we hv any options available for this........
thanks in advance...

Hi susan,
Below is the requested information,
Release : ECC 6.0
we are working on custom WF for ECO creation(CC01).
Description,
ECO is created in SAP by legacy system, thru bapi CCAP_ECN_CREATE, the WF will take the editing of the material in that ECO to different departments like MRP, accounting, sales,quality etc.... & respectively creates the views.
we cannot use CREATE event, bcos first the ECN(CC01) is created by bapi & further bapi creates the material & inserts it into ECN again, which is CHANGING the document. once this is done, our WF should trigger.
As we dont have CHANGE event in ECM BO, i am using CREATE event & settting it for ON CHANGE in SWEC t-code.
Bottomline is , it is triggering as soon as any changes happens.
But, we want it to restrict for one time triggering.
Regards.

UploadedFile & https Only work first time upload ????

I am using 10.1.3.4 Jdev. I use UploadedFile interface to upload files from local PC and ftp files to unix server. My "upload" web page works between my local PC and Unix server, but it only works first time upload file and ftp between
https server (application server--weblogic 10.0) and Unix server. If I just use http without SSL and my codes work fine you can upload file as many times you want and ftp them to Unix server. I used FTP not sftp to transfer files from application server to unix server. Can anyone shed some lights on my head ???? Thx.

Yes. I changed my code to SFT from ftp. it works. Thx. This URL for sftp: http://www.jcraft.com/jsch/ and is very good .

Taking action only the first time an event executes

I want a certain action to occur only the first time an event handler for a button is called. Is there a simple way to do this?
Bill F

There are two pretty easy ways to do this.
If you want to continue to trap other events (other event cases in your event structure), use a shift register:
1. Add a shift register to the loop containing your event structure. (right-click on the left-hand border of your loop and select Add Shift Register).
2. Wire a numeric constant = 0 from outside the loop to the input (left-hand) terminal of your shift register.
3. Inside your event structure, in the event case you want to handle only once, put a case structure around the code you want to execute only once. That code should be within the True case.
4. Add an Equal To 0? function (from the comparison palette) to the loop. Wire the input shift register to the input of Equal To 0?. Wire the output of Equal To 0? t
o the selctor for your new case.
5. Within the True case of your new case structure, add a numeric constant = 1. Wire that constant out to the output (right-hand) side of your shift register.
6. Within the False case of your new case structure, wire the input side of your shift register to the output tunnel created by the wiring in step 5.
This way the event structure will keep running and handling other events, but the case you just modified will only run the first time: the first time you get the event, the shift register will = 0 so you'll execute the True case of your new case structure. Within that case, you set the shift register to 1. The next time you get that event, the shift register = 1, not 0, so you'll execute the False case and not the code in your True case.
If you want to stop all event handling after the first event and your event handler is the only thing with its loop, from the event case (for the event you want to stop on), wire a True boolean constant out to
the Stop terminal of the loop containing your event structure.

App file sharing: files are displayed only the first time...

clicking somewhere else and then back to the application that you want to share files are not there any more.
I've to close and re-open the itunes in order to see them again.
itunes is running on windows 7 64bit.
is this a bug ?
thank you.

Hi! I have the same, exact problem. The files are displayed only the first time I look at the apps listed under File Sharing. If I look at another app on the list, the files on the one I previously checked are gone when I look at it again. Is there any way to fix this? I have a Lenovo X61s on Windows XP Professional 32 bit.

QuickTime launches slow but only the first time

QuickTime is slow in Mac OS 10.7, that's been widely discussed.
In my case, QuickTime is slow to open up a video file (MP4, AVI, WMV, etc,), but only the first time. After I've successfully opened up the one video file, all subsequent video files open up quickly, even after quitting QuickTime.
However, after a restart it's the same old situation again.
Is QuickTime installing something, then removing it when the computer shuts down?

Exception occurs only the first time

The server listens on a port to which client connects in applet mode. Every time client connects to server for the first time (i.e. after a fresh server installation), the client pops an exception:
java.io.InvalidClassException: javax.swing.ImageIcon$AccessibleImageIcon; local class incompatible: stream classdesc serialVersionUID = -3994512798706967451, local class serialVersionUID = -1903458698681874148.Subsequent client connects to server does not pop this exception. i.e. This occurs only for the first time.
Through posts in forum, I thought that this could be due to swing serialization incompatibility across version.(But in this application both server and client are on the same m/c having a single JRE and JDK, both are of version 1.4.2 )
But I am not able to reason out why the exception occurs only for the first time and then disappers in subsequent connects. ( despite clearing javaws cache and Browser cache and restarting server ... and it works on RMI mode).
What could be the reason ?

Hi
We recently changed our load balancer to a new load balancer. we get this error only after the load balancer change.
When the error occurs, I could see ORA-12571 error message only in the application error log. The listener.log has only the following message about TNS 12502. It does not have any message about ORA -12571.

Wait cursor appears only the first time... unless I don't move the mouse!

Ah yes, another cursor problem:
I am setting a wait cursor in my main JFrame when a key-release or a menu item click is detected (the time-consuming action is then triggered in a child JInternalFrame), and so far, it's been working great.
Then I noticed that the wait cursor only appears the first time the time-consuming action is called (or more precisely, if I never move the mouse, it happens every time as it should, but if I move the mouse, it only happens the first time! Ah, and I noticed I CAN move the mouse but ONLY when it is in the form of the wait cursor!).
Strangely, I can see the cursor blink briefly when the action is done, precisely when it should be changing back to the default cursor... what gives? If I close the child internal frame and re-open it, I can get the wait cursor again the first time only (again, unless I keep the mouse still, in which case it works great - argh).
Any ideas would be deeply appreciated!
Cheers!
PS - Here's a snippet of how we set the cursor, this is code in our main JFrame, called via either a keypress event or clicking on a menu item - mostly it's stuff that is unrelated, and we simply set the wait cursor as the very first line, so why in the world would it skip that line???? (the rest of the lines do in fact get executed):
private void refreshMenuItemActionPerformed(java.awt.event.ActionEvent evt) { doRefreshMenuItemAction(); }
private void doRefreshMenuItemAction() {
this.setCursor(new Cursor(Cursor.WAIT_CURSOR));
JDesktopPane desktop = (JDesktopPane)this.getContentPane().getComponent(0);
JInternalFrame activeFrame = desktop.getSelectedFrame();
try {
if ( activeFrame instanceof IDataDrivenForm ) {
((IDataDrivenForm)activeFrame).refresh();
} catch (Exception ex) {
ex.printStackTrace();
this.setCursor(new Cursor(Cursor.DEFAULT_CURSOR));

almost...
I now see that glasspanes are an answer to that question. I got it to work (almost) using a glasspane (see code snippet below). But what I can't quite grasp now is why this code does not work when I call it from a child (contained) dialog (and possibly internal frames as well)??? When I do so, the dialog freezes (the button I pressed doesn't even release) and the cursor does not change to waiting. This time I'm really not sure where to go next....
I appreciate anyone who has read this far, and would really be indebted to you for some good advice!
PS - Here's the nifty code, placed in my main JFrame class. I just substituted "this.setBusy(true);" for every place I was manually setting the WAIT_CURSOR in the past (and of course with matching setBusy(false)):
public final void setBusy(boolean isBusy)
Component glassPane = this.getGlassPane();
Cursor theCursor = isBusy ? Cursor.getPredefinedCursor( Cursor.WAIT_CURSOR ) : Cursor.getPredefinedCursor( Cursor.DEFAULT_CURSOR );
this.setCursor( theCursor );
glassPane.setCursor( theCursor );
glassPane.setVisible( isBusy );

Time machine would back up only the first time after I shut off my imac and started it up again. Then it would fail or claim it could not locate my external Hard Drive even though it's icon was showing in the time machine dialog window.

Time machine only ever backed up the first time it runs immediately after I start up my computer after it has been shut off. All other back up attemps fail. Recently it stopped recognizing the icon for my external hard drive in the time machine dialog window where you select the hard drive to back up to, and turn on and off the time machine function. Now the external HD icon only shows up on the desk top but no longer in the dialog box. I just tried shutting the computer off and turning it on again and now the light is on, on the external hard drive but the icon does not even appear on the desk top.
The external hard drive is a 1TB Seagate. The drive still has plenty of unused capacity. I ran a diagnostic test on it. It said the disk needed repair but the repair function would not work. The message stated that it could not be unmounted and repair is not available because the disk can't be written to. The Mac OX utility said the disk can still be opened but can't be changed nor repaired. The external HD is not S.M.A.R.T. supported.
I haven't tried replacing the cable yet. Is that the next thing I should try?

ADF Task Flow Exception Handling

Hi ,
I tried a very simple thing for taskFlow exception handling.
I created a bounded task flow with a page fragment (View1.jsff) and another view which is the TaskFlow ExceptionHandler (error.jsff).
The view1.jsff has a button whose action is bound to the backing bean. In the backingBean method I deliberately do division by 0.
Since this is an unHandled exception, I would have expected the control to come to error.jsff. But, instead I am shown a pop up box with the error message.
Why is the control not getting redirected to error.jsff ?
Thanks.

Hi Frank , im having the same problem.
I want to handle exceptions that occur while navigating task flows (example: A user navigates to a task flow that he/she does not have view permission)
I tried using a view activity and method activity as the exception handler but none of them works, the exception is still not handles. It does not even navigate to the exception handler on the task flow.
on the view page i have:
<af:panelStretchLayout topHeight="50px" id="psl1">
<f:facet name="top">
<af:panelGroupLayout layout="scroll"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
id="pgl1">
Error message:
<af:outputText value="#{controllerContext.currentRootViewPort.exceptionData.message}" id="ot2"/>
</af:panelGroupLayout>
</f:facet>
<f:facet name="center">
<af:outputText value="#{my_exception_Handler.stackTrace}" id="ot1"/>

</f:facet>
</af:panelStretchLayout>
I tried getting the error message and stacktrace from the controllerContext via EL like this "#{controllerContext.currentRootViewPort.exceptionData.message}"
and from the controllerContext class in functions that i have declared in my_exception_Handler class like this
" ControllerContext ctx = ControllerContext.getInstance();
ViewPortContext vCtx = ctx.getCurrentViewPort();
if(vCtx.getExceptionData() != null){
StringWriter stringWriter = new StringWriter();
PrintWriter printWriter = new PrintWriter(stringWriter);
vCtx.getExceptionData().printStackTrace(printWriter);
return stringWriter.toString();"
But all this dont even matter because when the exception occurs on the task flow it does not navigate to the default exception handler.
thanks for your interest and help in advance.

Task flow exception handler

Hi all,
I'm trying to specify a method activity as an exception handler in the adfc-config. The problem is if I specify a view activity or a bounded task flow as the exception handler then it works fine, but if the exception handler is a method activity then it is not recognized. What could be the cause?. I need to execute a method when an exception occurs.
Version: 11.1.2.0
Edited by: NewBee on Apr 23, 2013 10:37 AM

Hi,
there should not be a problem with this and I recently did the same with JDeveloper 11g R2 (not sure which version of JDeveloper you use because you did not share this information). I assume you just marked the method activity as an exception handler without any other configuration? If so then set a break point to the managed bean method that you access from the method activity to see if it actually stops there. Also note that not all exceptions are handled by the controller exception handler. E.g an exception during render response phase (typically an exception in a managed bean) is not handled by the controller. Also you need to avoid the managed bean that handles the exception to itself throw one. This however you will see when debugging the bean.

Hyperlinks work only the first time clicked when published

I am using hyperlinked text captions for slide navigation within a course. I have placed the text hyperlinks on the master slides so they appear throughout. The hyperlinks either link to an external pdf (job aid) or to another slide within the course.
When I publish the course, the hyperlinks only work the first time they are clicked. All other times, I get the hand cursor when I roll over them, but nothing happens when I click. Is there a setting somewhere to allow for infinite clicks on they hyperlinks?

Hi there
Odd that this would happen. There is no setting I'm aware of that determines the number times a link may be clicked.
My guess is that something else is going on. Normally, the slide is paused when the link is clicked. Is this the case for you? One thought is that by clicking the link, the pause is released and perhaps the link is then no longer active because the playhead reached a different spot?
Cheers... Rick

BATCHINPUT: Screen appears only the first time

Hi everybody,
I have the following situation in R/3:
On transaction ABZON when the user selects this transaction for the first time, appears a window asking for the company field (BUKRS). If the user enters the same transaction again without login off, that window doesn't appears going directly to the transaction's main screen.
The problem is that I have to make a batch input of this transaction but doesn't want the user to logoff every time it needs to run the batch input again.
How can I avoid that screen to appear or force the batch input to always show that screen.
If anyone can help me will be appreciated.
Thanks,
Orlando.

Orlando, I've ran across this is same problem in another transaction. What I did was I "separated" the transaction. Meaning the first thing that happens when the transaction runs, is to take care of the window that appears only once during a log on session. Then later when doing the BDC to actually do something, it will not need to have this part of the recording.
So for example, do your recording for the window that pops up enter a value, and back out of the transaction. Call this BDC code before doing any of the rest of the transactions. Not that the value is filled, it will not pop up again during the rest of the session. Call your BDC to process the rest of the transaction.

RemoteObject FAULT handled only the first time

I'm creating RemoteObject and then handling the fault event
myRemoteObject.addEventListener(FaultEvent.FAULT,
faultHandler);
protected function traiterFaute(event:faultHandler): void
CursorManager.removeBusyCursor();
mx.controls.Alert.show("An error has occured");
Why this event is only handled the first time ?? So in this
cas the Alert Box is appearing only on the first fault !!!
Is it normal ,

I ended up creating a new RemoteObject on each request. Seems
terribly inefficient, but it's the only thing that worked.

Permissions issue only the FIRST time I try to overwrite a file.

I've a standard user account and I've found overwriting protected files is bugged in Leopard.
As an example: every time I'm upgrading Camino web browser with the latest nightly build (by dragging the new version from it's disk image, and into the Applications folder) I get a permissions issue the first time only. As usual I am warned I will need to authenticate, then I am warned I will be replacing a file, then the first time only I get told I do not have sufficient privileges on one or more items to continue. The second time I try I am allowed to progress to the authentication window where I enter my admin username and password and the operation completes.
The same thing happens with other files I'm trying to overwrite that are located in protected folders (I just use Camino as an example because it is a daily occurrence). But it ONLY happens the first time.
This has persisted through three erases of my brand new iMac's HD and clean installations of Leopard. I have of course run Disk Utility multiple times to repair the HD (no errors found) and repair permissions (just the usual ACL errors every Leopard user faces).

Hi,
What's the error message did you get? It would be better to provide a screenshot for your problem.
Generally speaking, this problem can be caused by third party adds-on of IE. You can try to start IE with no adds-on mode for test.
Open run, type iexplore -extoff, pess
Enter.
If it works properly, please chck which plugin enabled in your browser, try to disable them for test.
In addition, this can also be caused by IE settings, try to reset IE for test.
