I am currently trying to clear up a mess where a new starter has (almost) completed a change, so it's been through review/rework and is ready for deliver, but in the meantime, like most people familiar with modern SCM systems, he's just started a new activity on the same view. (and he's on leave)
I believe the solution to this is to move the new activity with its changeset to a new view and then deliver the old activity as intended.
However I have read how to "move" an activity between streams, but I can't find in the IBM docs or anywhere else how to move it with the changeset.
Now, the fallback option is to manually copy over the change and remove it from the first view. I'd rather not do this as that adds dev and review effort, but if it is the only way, then I'll do it.
