Hi all,

I have working fine the Participant plugin (Create approvers: http://rsjazz.wordpress.com/2012/11/30/a-create-approval-work-item-save-participant/) but when I try to attach a file in a workitem (after creation) an alert say "Failed save workitem".

The ccm.log error:

2013-05-22 11:32:08,951 [ WebContainer : 3] ERROR com.ibm.team.process.common - com.ibm.team.workitem.common.internal.model.impl.AttachmentImpl incompatible with com.ibm.team.workitem.common.model.IWorkItem

java.lang.ClassCastException: com.ibm.team.workitem.common.internal.model.impl.AttachmentImpl incompatible with com.ibm.team.workitem.common.model.IWorkItem

at ev.createapproval.CreateApproval.run(CreateApproval.java:101)

My first lines of run code:

//Get Data

Object data = operation.getOperationData();

ISaveParameter saveParameter = null;

if (data instanceof ISaveParameter)

{

saveParameter = (ISaveParameter) data;

IWorkItem newState = (IWorkItem) saveParameter.getNewState(); //line 101 error

Identifier<IState> newStateId = newState.getState2();

Identifier<IState> oldStateId = null;

IWorkItem oldState = (IWorkItem) saveParameter.getOldState();

String tipo = newState.getWorkItemType().toString();

//avoid recursive with loop

if (saveParameter.getAdditionalSaveParameters().contains("Loop") || !(tipo.equals("proyecto")))

{

return;

}

//Not new wi

if (oldState != null )

{

IApprovals HasApprovals = oldState.getApprovals();

List<IApproval> hasAppr = HasApprovals.getContents();

...

Anybody know what is wrong with my participant plugin?

Thanks

I dont understand why the follow up action start if I dont "Save" the Workitem? I only "Attach a File"...

Attaching a file saves a work item you attach it to.

Marcos, if you look into the code of the participant: http://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/ and the other one, where you commented, you can see that you have to make sure your follow up action is actually triggered by a work item save. The code mentioned is:

		if (!(data instanceof ISaveParameter))
			return;

		// Check that this was a save operation on a work item
		ISaveParameter saveParameter= (ISaveParameter) data;
		if (!(saveParameter.getNewState() instanceof IWorkItem))
			return;

The instanceof IWorkItem is actually important, so you don't cast something completely different than a IWorkItem and get the error you see.
