copy/paste in sequence diagrams

[danch]

When I try to select a number of lifelines/objects and messages in a sequence diagram, I find that selecting a message generally de-selects any other objects, even when I ctrl-select. Select all only selects the lifelines, not the messages. This effectively makes it impossible to do copy/paste from one sequence diagram to another.

Am I missing something or is this a bug?

thanks,

OK, I've found 'Copy Diagram to Clipboard' on the context menu in the Project View. Now if 'Paste Diagram...' were available on Use Case Realizations, I'd be ... well, on my way to happiness. The only dodgy bit then would be that the paste operation insists on cloning all objects that are on the diagram, thinking that the diagram (rather than the realization) owns them.

I believe my workaround will be to break up my Realization into multiple realizations, then copy the diagram through a temporary folder. I'll have one sequence per Realization then, which is not exactly what I had in mind, but is certainly workable.
