[Uml-user] UMI Question re: UMLAssocWidget tag

[Mark Priest]

John,

Thanks for your help.  I'm afraid that those fields must mean something a 
little different.  I tried to rectify them with my drawings but I could not 
figure out the logic. I probably don't need to know after all but if I do I 
will look into the code since you've given me a head start.

Take care,
Mark
