I can't figure out how to label a transition (arrow) in a UML Statechart. With most items, I just start typing, but with the transition it says:
Shape protection and/or layer properties prevent complete execution of this command.
I found Format -> Protection and unchecked the "Text" check box, and now I can start typing, but the text just goes away when I finish. What's up with that?
One thing that sort of works is a "Guard expression", but I don't think that's quite what I want. Unlike this MSDN example, it has awkward square brackets around it. Is there any way to get a normal-looking label for transitions?
