I have 2 streams, TEST and MAINT, that both flow into BASE.  We use TEST as our development stream and MAINT as our maintenance stream.  When something is delivered from either stream to BASE, those changes are then delivered to the other stream to keep them in sync.

There was a change set accidentally delivered to TEST that should not have been delivered.  Because it would have affected our maintenance stream we did not deliver the changes to BASE right away, but intended to deliver both those changes and a change set to reverse it at the same time after the changes in MAINT were completed.  One module was modified by the accidental delivery and the changes in MAINT.  We are now trying to sync up the MAINT and TEST streams, but I cannot accept the changes because of the common module.  Outgoing changes on that module (the accidental change and its reversal) and incoming changes on that module (from BASE) are pending.

When I try to deliver to BASE, the error suggests to accept all incoming changes, resolve the conflicts, and try delivering again, but I cannot accept the changes.  It is a stream, not my workspace, so I cannot make changes.

When I try to accept the incoming change, the error suggests to accept the changes into a workspace, resolve the conflicts, then deliver the merged changes.  I cannot accept anything into a workspace because there are no incoming changes to accept.  All of the change sets have already been accepted and there is no conflict to resolve at the workspace level.  The conflict is in the stream.

I tried to "Reverse" the outgoing change from TEST, but the patch is just put in the list of changes waiting to be accepted.

How can I get it to accept the changes?  I also need to either deliver the other changes or cancel them out, but I need to figure out how to get the code flowing again.  If I could reject the incoming change that would be helpful, but I understand that is not available yet.  Is there anything I can do other than deleting a stream and recreating everything?
