Thanks. I think my question is regarding on this method:

findLinksByTarget(java.lang.String[] linkTypeIds, IReference target, IProgressMonitor monitor)

From the sample code :
linkManager.findLinksByTarget("com.ibm.team.filesystem.workitems.change_set", workItemReference, monitor);

The target is set to com.ibm.team.filesystem.workitems.change_set. The method returns the link of the changeset associated with the workitem.

My question is if I want to retrieve the link of the related worktitem assoicated to the original workitem (parent, children, related, etc), I would expect we have to set the target to one of the following:

public static final String RELATED_WORK_ITEM= "com.ibm.team.workitem.linktype.relatedworkitem"; //$NON-NLS-1$
public static final String DUPLICATE_WORK_ITEM= "com.ibm.team.workitem.linktype.duplicateworkitem"; //$NON-NLS-1$
public static final String COPIED_WORK_ITEM= "com.ibm.team.workitem.linktype.copiedworkitem"; //$NON-NLS-1$
public static final String RELATED_ARTIFACT= "com.ibm.team.workitem.linktype.relatedartifact"; //$NON-NLS-1$
public static final String ATTACHMENT= "com.ibm.team.workitem.linktype.attachment"; //$NON-NLS-1$
public static final String BLOCKS_WORK_ITEM= "com.ibm.team.workitem.linktype.blocksworkitem"; //$NON-NLS-1$
public static final String PARENT_WORK_ITEM= "com.ibm.team.workitem.linktype.parentworkitem"; //$NON-NLS-1$


Thanks.

I'm not sure I understand the question:
> If my assumption is correct what would be the link type name, which returns the ILink objects.

The ILinkManager.find* methods can be used to find any kind of links between two items. ILink is the type of object returned in all cases. An ILink represents a link between a source reference and a target reference, where a reference (IReference) may be either an item reference (item handle) to an item in the same repostiory, or an URI reference (arbitrary URL, sometimes used to refer to items in other repositories).

In the case of the "com.ibm.team.filesystem.workitems.change_set" link type id, the source reference is a change set handle (IChangeSetHandle) and the target is a work item handle (IWorkItemHandle).

To search for change sets associated with a given work item, you'd use findLinksByTarget. To search for work items associated with a given change set, you'd use findLinksBySource.

To get the resulting item handles from the ILinks in the result, use:

IReference ref = link.getSourceReference(); // or getTargetReference()

if (ref.isItemReference()) {

  IItemReference itemRef = (IItemReference) ref;

  IItemHandle itemHandle = itemRef.getReferencedItem();

}

Then cast the itemHandle down to IChangeSetHandle or IWorkItemHandle as appropriate.

Nick,

I tried to run the following code.

By running in the debug mode:

There is an object returned by this method:
linkQueryPage = linkManager.findLinksByTarget("com.ibm.team.workitem.common.model.WorkItemLinkTypes.RELATED_WORK_ITEM", workItemReference, monitor);

Now when the code proceeds on this method it returns null.
ILinkCollection linkCollection = linkQueryPage.getAllLinksFromHereOn();

There are two different workitems (APAR workitem 54, APAR subTask 55) and I set the Related link between 54 and 55.

Any advise?
