[URGENT] RTC - Infinite post call loop problem


benjamin oh (144) | asked Apr 24 '13, 3:19 a.m.
Hi !


I am developing some participants.  I get a error message as follows.

* Error message:
The server is not responding or a page navigation occurred before an operation completed.
Check that your server connection is working and that the server is operational,
then try the action again or refresh the page.

I do not know the reason of it, but I guess it is from infinite post call loop.
* I found the guess with log.
The participant is activated in same state.
If user request saving with web page save button, the plugin is called.
It is ended with updating a attribute value of same workitem in same state.  At that point,
there is infinite post call loop.  So RTC display message as above in a few minutes.


Is there any person who experienced this error in the past ?    Help me !

You may want to look at the application server logs like SystemOut.log or catalina.log and ccm.log for errors. Posting errors from the logs might give better clues. If I have to guess, this error can come due to memory issues as well.

I reenact this problem in the JKE Banking sample project.
I can also find an infinite loop calling in the console as follows.

* We do not use if-clause as follows to save workitem in same state.

       if(oldState.equals(newState) == false)

 

* Participant source :

            IWorkItem newWorkItem = (IWorkItem) saveParameter.getNewState();
            IWorkItem oldWorkItem = (IWorkItem) saveParameter.getOldState();
           
            String workitemType = newWorkItem.getWorkItemType();
           
            // In story workitem case
            if(workitemType.equals("com.ibm.team.apt.workItemType.story")){
                System.out.println("WORKITEM - " + newWorkItem.getId());
               
                Identifier<IState> newStateId = newWorkItem.getState2();
                Identifier<IState> oldStateId = oldWorkItem != null ? oldWorkItem.getState2() : null;
               
                String newState = newStateId.getStringIdentifier();
                String oldState = oldStateId != null ? oldStateId.getStringIdentifier() : null;
               
                System.out.println("oldState=" + newState);
                System.out.println("newState=" + oldState);

                IWorkItem wiCopy = (IWorkItem) getService(IWorkItemServer.class)
                            .getAuditableCommon()
                            .resolveAuditable(newWorkItem, IWorkItem.FULL_PROFILE, monitor)
                            .getWorkingCopy();
                   
                // Set Description
                wiCopy.setHTMLDescription(XMLString.createFromPlainText("test description ..."));
                   
                // save workitem
                Set<String> additionalParams = new HashSet<String>();
                additionalParams.add(IExtensionsDefinitions.LSG_AMS_EXTENSION_ID);
                   
                getService(IWorkItemServer.class).saveWorkItem3(wiCopy, null, null, additionalParams);
                System.out.println("Setting description is completed ...");
