[mylar-dev] Getting "Stale Editor" after adding attachment

["Lubos and Alena Pochman" <pochmans@xxxxxxxxx>]

I am getting "Stale Editor" after adding attachment to the repository task:
"Stale Editor", "Remote copy of task has changes. Refresh and open report?"

I implement org.eclipse.mylar.tasks.core.IAttachmentHandler#uploadAttachment
 in CodeBeamerAttachmentHandler implements IAttachmentHandler and do:

            String bugId = AbstractRepositoryTask.getTaskId(task.getHandleIdentifier());
            ICodeBeamerClient client = connector.getClientManager
().getRepository(repository);
            client.postAttachment(bugId, comment, description, file, contentType, isPatch);

How do I force the editor update without getting the "Stale Editor"?

Thanks, Lubos Pochman
