Hi,

I have realized I follow-up action that run without problem on RTC. In this server side plug-in I create a new work item and add it as a child of my auditable workitem when I try to save it.

public class CreaTask extends AbstractService implements IOperationParticipant  {

	

	public void run(AdvisableOperation operation, IProcessConfigurationElement participantConfig,IParticipantInfoCollector collector, IProgressMonitor monitor)

                throws TeamRepositoryException

 { 		Object data= operation.getOperationData();

		if (data instanceof ISaveParameter) {

			IAuditable auditable = ((ISaveParameter) data).getNewState();

			if (auditable instanceof IWorkItem) {

				IWorkItem workItem = (IWorkItem) auditable; 

				String tipo = workItem.getWorkItemType().toString(); //Trovo il tipo di WorkItem Release

					IWorkItemServer workiteamServicess = getWorkItemServerService();

				if(tipo.contains("release")) { 

					IProjectAreaHandle progetto = workItem.getProjectArea();										

					

					String NOME_BOX_TASK[] = ....

					String ID_TASK[] = .....

					String NOME_TASK[] = .....

					int num_task = NOME_BOX_TASK.length; int j = 0; int i = 0; IAttribute taskbox_status; 

					IWorkItemType task_type;	Boolean task_result; IWorkItemReferences references; IWorkItem workItemCopy; IWorkItem workItemTASK; 

					references = workiteamServicess.resolveWorkItemReferences(workItem, null); IWorkItem workItemCopy2;

					workItemCopy = (IWorkItem) workItem.getWorkingCopy();

					for (i=1; i<num_task; i++){

						taskbox_status = workiteamServicess.findAttribute(progetto, NOME_BOX_TASK[j].toString(), monitor);

						task_type = workiteamServicess.findWorkItemType(progetto, ID_TASK[j].toString(), null);

						task_result = (Boolean) workItem.getValue(taskbox_status);

						

						if (task_result) {

							workItemTASK = workiteamServicess.createWorkItem2(task_type);

							workItemCopy2 = (IWorkItem) workItemTASK.getWorkingCopy();

							workItemCopy.setHTMLSummary(XMLString.createFromPlainText("T_"));

							workiteamServicess.saveWorkItem2(workItemCopy2, null, null);

							references.add(WorkItemEndPoints.CHILD_WORK_ITEMS, WorkItemLinkTypes.createWorkItemReference(workItemTASK));

						

						} 

						j++; } 

					workiteamServicess.saveWorkItem2(workItemCopy, references, null); 

					

				} 

			} 

		} 

	}

	



private static IWorkItemServer workiteamServer;



private IWorkItemServer getWorkItemServerService() {

		synchronized (this) {

			if (workiteamServer == null) {

				workiteamServer = getService(IWorkItemServer.class);

			}

			return workiteamServer;

		}

	}		

} 

But, when I add a precondition on the same auditable workitem save operation like the follow

public class ControlloTaskSV_or_WKFL extends AbstractService implements IOperationAdvisor {

	

	private static IWorkItemServer workiteamServer = null;

	

	public void run(AdvisableOperation operation, IProcessConfigurationElement advisorConfiguration, IAdvisorInfoCollector collector, IProgressMonitor monitor)	

		throws TeamRepositoryException {

		

		Object data= operation.getOperationData();

		if (data instanceof ISaveParameter) {

			IAuditable auditable = ((ISaveParameter) data).getNewState();

			if (auditable instanceof IWorkItem) {

				IWorkItem workItem = (IWorkItem) auditable;

				IProjectAreaHandle progetto = workItem.getProjectArea();

			

			    IAttribute taskbox_status;

				taskbox_status = getWorkItemServerService().findAttribute(progetto, "Rel_task_svwfnav", monitor);

				Boolean taskSV_result = (Boolean) workItem.getValue(taskbox_status);

				taskbox_status = getWorkItemServerService().findAttribute(progetto, "Rel_task_wkfl", monitor);

				Boolean taskWKFL_result = (Boolean) workItem.getValue(taskbox_status);

			      if(taskSV_result && taskWKFL_result) {

					IAdvisorInfo info = collector.createProblemInfo("Warning", "worning ", "error");

					collector.addInfo(info);} else { return;

				}

			}

		}

	}

	

private IWorkItemServer getWorkItemServerService() {

			synchronized (this) {

				if (workiteamServer == null) {

					workiteamServer = getService(IWorkItemServer.class);

				}

				return workiteamServer;

			}

		}	

	

	

}

I have an error on the workiteamServicess.saveWorkItem2(workItemCopy2, null, null) of the follow-up action.

Somebody can help me to fix this error?
