Hi all,

I got the following issue when opening one of my Eclipse BPMN2 Files:

MessagFlow id ="MessageFlow1 Source and Target Shapes do not exist"

This "warning" comes for many Shapes and I do not know how to delete them. Would be very thankful for your help on how to delete unused Shapes...

Thank you all,
Bran

Hmm, the question isn't how to delete the MessageFlows that reference undefined Shapes, it's how did the referenced Shapes disappear in the first place? Are you able to reproduce the steps that led to the corruption of this file?

Thanks for your reply,

No i cannot go back to these steps. Is there an option where I can see all unused MessageFlows? I really donĀ“t know where they are.

Bummer. If you happen to run across this situation again, I'd appreciate it if you could open a bugzilla and attach before & after snapshots of your process file.

Because MessageFlows require a source and target BPMN element, the file importer can not render any unattached flows because it does not know where to attach them. What you will see, though, is an error popup dialog (as you've already described earlier) and these flows will automatically be removed when you save the file.

Thanks!
Bob
