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

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi James,

What do you mean by "fail to show" ?   Could there be an issue in the code
used to render your sequence diagram?
Are there exceptions being thrown from opensource code?
Your first message is called "createMessage", are you perhaps trying to
create "create messages" in the middle of your diagram?

I'm not sure if this is an opensource issue.

Could you post your model so I can inspect the entire contents.

Cheers,

- James.
