How to programmatically add Related Change Request link?

Cecilia Lindgren (43●12●13) | asked Jan 11 '11, 11:52 a.m.
I have created an operation Advisor that is communicating with an external system using OSLC interface. Now I need to save a link to the other system.
Is there any way to programmatically add a Related Change Request link to the workitem?

I am using RTC 2.0.02 iFix 5.

No, all examples in the document references to code on client side. I need to be able create a link to the workitem in the save operation for the Operation Advisor on the server side.

OK -- might not be the best way, but code below is working (tried using RTC 3) .. and some lessons learned.

1. See https://jazz.net/wiki/bin/view/Main/RTCSDK20_ProcessPreConditionExample and the example https://jazz.net/wiki/pub/Main/RTCSDK20_ProcessPreConditionExample/advisor-example.zip
2. To get access to services for creating items etc - make your handler a subclass to the AbstractService. And to get access to services in the advisor you must ask for them as preconditions. See example below 

<plugin>

   <extension

         point="com.ibm.team.process.service.operationAdvisors">

      <operationAdvisor

            class="com.ibm.ecat.exampleadvisor.LinkCreationTest"

            id="com.ibm.ecat.exampleAdvisor.prohibitSave"

            name="Creating Parent 2"

            operationId="com.ibm.team.workitem.operation.workItemSave">

         <extensionService

               componentId="com.ibm.ecat.exampleAdvisor.linkCreationTest2"

               implementationClass="com.ibm.ecat.exampleadvisor.LinkCreationTest">

            <prerequisites>

              	<requiredService interface="com.ibm.team.workitem.service.IAuditableServer" /> 

  				<requiredService interface="com.ibm.team.workitem.service.IWorkItemServer" /> 

            </prerequisites>            

         </extensionService>            

      </operationAdvisor>

   </extension>



</plugin>


3. And a code snippet with an advisor that creates a Parent & and link to the new parent each time the item is saved (note: needs to turn off the FiledAgainst precondition for SaveItem to have this work) 


package com.ibm.ecat.exampleadvisor;



import java.util.Collections;



import org.eclipse.core.runtime.IProgressMonitor;

import org.eclipse.core.runtime.IStatus;



import com.ibm.team.foundation.common.text.XMLString;

import com.ibm.team.process.common.IProcessArea;

import com.ibm.team.process.common.IProcessConfigurationElement;

import com.ibm.team.process.common.IProjectArea;

import com.ibm.team.process.common.IProjectAreaHandle;

import com.ibm.team.process.common.advice.AdvisableOperation;

import com.ibm.team.process.common.advice.IAdvisorInfoCollector;

import com.ibm.team.process.common.advice.runtime.IOperationAdvisor;

import com.ibm.team.repository.common.IAuditable;

import com.ibm.team.repository.common.TeamRepositoryException;

import com.ibm.team.repository.service.AbstractService;

import com.ibm.team.workitem.common.ISaveParameter;

import com.ibm.team.workitem.common.model.IWorkItem;

import com.ibm.team.workitem.common.model.IWorkItemReferences;

import com.ibm.team.workitem.common.model.IWorkItemType;

import com.ibm.team.workitem.common.model.ItemProfile;

import com.ibm.team.workitem.common.model.WorkItemEndPoints;

import com.ibm.team.workitem.common.model.WorkItemLinkTypes;

import com.ibm.team.workitem.common.model.WorkItemTypes;

import com.ibm.team.workitem.service.IAuditableServer;

import com.ibm.team.workitem.service.IWorkItemServer;



public class LinkCreationTest extends AbstractService implements IOperationAdvisor {

	public static final String PROBLEM_TYPE = " HelloWorldAdvisor.prohibitSave";



	public void run(AdvisableOperation operation,

			IProcessConfigurationElement advisorConfiguration,

			IAdvisorInfoCollector collector, IProgressMonitor monitor)

			throws TeamRepositoryException {



		Object data = operation.getOperationData();



		if (data instanceof ISaveParameter) {

			ISaveParameter param = (ISaveParameter) data;

			IAuditable auditable = param.getNewState();

			if (auditable instanceof IWorkItem) {

				IWorkItem sourceworkItem = (IWorkItem) auditable;

				if (sourceworkItem.isNewItem())

					return;

				

				IProcessArea processArea = operation.getProcessArea();

				IProjectAreaHandle projectAreaHandle = processArea.getProjectArea();

				

				IAuditableServer auditableServer= getService(IAuditableServer.class);

				IProjectArea projectArea= auditableServer.resolveAuditable(

						projectAreaHandle,

						ItemProfile.<IProjectArea>createFullProfile(IProjectArea.ITEM_TYPE),

						monitor);



				createWorkItem(projectArea, "Parent to " + sourceworkItem.getId(), sourceworkItem);				

			}			

		}

	}	

	

	private IWorkItem createWorkItem(IProjectArea projectArea, String summary, IWorkItem source) throws TeamRepositoryException {

		IWorkItemServer workItemServer = getService(IWorkItemServer.class);

		IWorkItemType defectType = workItemServer.findWorkItemType(projectArea, WorkItemTypes.DEFECT, null);

		

		IWorkItem workItem= workItemServer.createWorkItem2(defectType);

		workItem.setHTMLSummary(XMLString.createFromPlainText(summary));

		

		IWorkItemReferences references= workItemServer.resolveWorkItemReferences(workItem, null);

		references.add(WorkItemEndPoints.PARENT_WORK_ITEM, WorkItemLinkTypes.createWorkItemReference(source));



		System.out.println("Create work item " + summary +  ": " + workItem.getItemId().getUuidValue());

		

		long saveStart= System.currentTimeMillis();

		IStatus status= workItemServer.saveWorkItem3(workItem, references, null, Collections.<String>emptySet());

		System.out.println("Save total: "+ (System.currentTimeMillis() - saveStart));

		if (status.matches(IStatus.ERROR)) {

			throw new TeamRepositoryException(status.getMessage());

		}

	

		return workItem;

	}	

	

}


So in summary: Some snippets that might get you in the right direction.

Follow up question from celin:
===
Now I had time to test your example and got it to work, but unfortunately it does not address the problem I have, I want to add a Change Management link to the current workitem.
I have not found how to create a IEndPointDescriptor of the type that the reference to MHWeb becomes, to use the code below.
I have resolved the references and see that id = "relatedChangeManagement" for this type EndPointDecsriptor when we sent the link to the RTC from Mhweb by passing the tag
<oslc_cm>

references.add(WorkItemEndPoints.PARENT_WORK_ITEM, WorkItemLinkTypes.createWorkItemReference(source));
===

So -- how to find the way of programmatically create a link of Change Management linktype?

Something like this may work, where you create a link of WorkItemLinkeTypes.RELATED_CHANGE_MANAGEMENT 


ILinkManager linkManager= (ILinkManager) repo.getClientLibrary(ILinkManager.class);

			

IItemReference sourceRef= IReferenceFactory.INSTANCE.createReferenceToItem(source.getItemHandle());

IItemReference targetRef= IReferenceFactory.INSTANCE.createReferenceToItem(target.getItemHandle());

ILink link= ILinkFactory.INSTANCE.createLink(WorkItemLinkTypes.PARENT_WORK_ITEM, sourceRef, targetRef);



			

linkManager.saveLink(link, monitor);

For advisors, the solutions above don't work to add link to current work item.

What you have to do in this case is only that: 


Object data = operation.getOperationData();

ISaveParameter saveParameter = (ISaveParameter) data;



IWorkItemReferences references = saveParameter.getNewReferences();

Reference reference = (Reference)IReferenceFactory.INSTANCE.createReferenceToItem(wiParent);

references.add(WorkItemEndPoints.PARENT_WORK_ITEM, reference);


You don't need to save anything to edit the current work item because you are already in a save operation.
