[news.eclipse.tools.uml2] Re: questions about creating sequence diagram

[ganzhi@xxxxxxxxx]

Hi James

I finally resolved this error by myself. I created a SynchCall message but I haven't created a reply message. So when I try to show the interaction in
Rational tool, it generates this error.

Thanks a lot for you help!
