How to fetch change set data from links

Question

I am using the below code :

for(Object wI : links){

ILink link = (ILink) wI;

Object source = link.getTargetRef().resolve();

IItemHandle changeSetHandle = (IItemHandle) link.getTargetRef().resolve();

if (source instanceof IChangeSetHandle) {

changeSet = (IChangeSet) repo.itemManager().fetchCompleteItem(changeSetHandle,

IItemManager.DEFAULT, monitor);

System.out.println("changeset---1"+changeSet);

}

}

But there is some exception like :
com.ibm.team.repository.common.ItemNotFoundException: CRJAZ0215E The following record was not found in the database: com.ibm.team.scm.common.internal.impl.ChangeSetHandleImpl

The source code is totally messy; source and changeSetHandle seem to be the same thing and why would you test the instance for one and then use the other item to resolve?

Cast the item you want to look up to IChangeSetHandle and use the casted interface in the lookup.

This is code that worked for me

        IWorkItemReferences wiReferences = workItemCommon
                .resolveWorkItemReferences(workItem, monitor);
        List<ichangesethandle> changeSetHandles = new ArrayList<ichangesethandle>();
        List<ireference> references = wiReferences
                .getReferences(ILinkTypeRegistry.INSTANCE.getLinkType(
                        WorkItemLinkTypes.CHANGE_SET)
                        .getSourceEndPointDescriptor());
        for (IReference reference : references) {
            if (reference.isItemReference()) {
                IItemHandle refItem = (IItemHandle) reference.resolve();
                if (refItem instanceof IChangeSetHandle) {
                    changeSetHandles.add((IChangeSetHandle) refItem);
                }
            }
        }
    @SuppressWarnings("rawtypes")
    List changeSets = itemManager.fetchCompleteItems(changeSetHandles,
            IItemManager.DEFAULT, monitor);
    for (Object object : changeSets) {
        if (object instanceof IChangeSet) {
            IChangeSet changeSet = (IChangeSet) object;

.........
</ireference></ichangesethandle></ichangesethandle>

@Ralph I have some change sets which have link type id : com.ibm.team.workitem.linktype.scm.tracksChanges
and then I am using the code which you have shared but it returns null value and exception that the item is not found in the database even though the change set is there.
Any help would be appreciable.

Surely there is some issue in this line :

List changeSets = repo.itemManager().fetchCompleteItems(changeSetHandles,

IItemManager.DEFAULT, monitor);
I have URIReference of change sets. Is there any other way to fetch URI references?

The code I shared works for me. I don't get null pointers and I am passing an array of the IChangeSetHandles to the call you surely say to be wrong and NOT the references.

I can not remote debug.

I have reference.isURIReference() type, shall I use the same code to fetch complete change set?

It's all about the answers!
