Hi All,
I have to identify if a changeset exists in any stream,prior to creating a new one - so, i am retrieving the uuid during the creation and using it further. I tried using "haschangesets" method to find if a workspace or stream contains a changeset with a particular uuid. code snippet as below:

UUID uuid1 = UUID.valueOf(fChangeSet.getItemId().getUuidValue());
        IChangeSetHandle csHandle = (IChangeSetHandle) IChangeSet.ITEM_TYPE.createItemHandle(uuid1, null);
        IChangeSet csNEW = (IChangeSet) teamRepository.itemManager().fetchCompleteItem(csHandle, IItemManager.REFRESH, monitor);
        cs.add(csHandle);
        if(fWorkspace.hasChangeSets(cs, monitor))
 
It doesnt locate an existing changeset -> I tried with both Changeset and the handle as well.

2. I also tried using changeset-searchcriteria , but couldn't find an option to search by UUID, ItemID or comment.

Please advise.
Thanks
