We're using UCM and have set up hudson to build some developer's streams. Hudson uses a snapshot view on the stream that is not the view the developer works with. When the developer rebases through the dev view, the stream (and the dev view) get updated to the new foundation baseline. However, the snapshot view still has the old baseline in it. When cleartool update is run by hudson on the snapshot view, not all the new files in stream will be copied into the snapshot. The solution is to run ct setcs –stream before updating the snapshot view in hudson.
