[Uml-devel] Question about an error I am getting.

[REYNOLDS,JOHN (HP-Boise,ex1)]

I am trying to use umbrello to create a class diagram.

When I click on any class in my diagram, it popping up a dialog box titled
"Association error! - Umbrello UML Mo"
With a message of "Incorrect use of associations."

However, there is no clue given about what is wrong.  Furthermore, it seems
to happen on every class now, when before some classes were OK. Even classes
I haven't changed are wrong.

Also, the Umbrello UML Modeller Handbook has one kind of arrow for an
association, and one for aggregation. But, the tool has more choices than
that. What are the differences between the association choices?  How can I
figure out why the tool thinks my diagram is wrong (it probably is, but I
would like to know why)?

Thanks,

John Reynolds
