Description Sergey Petrov 2006-07-05 09:14:31 UTC
UML2.0 superstructure descibes ternary associations, we do not support the
feature, see users feedback on prev release:
Please help. I need to depict a ternary association icon between 3 Classes in my
Class diagram.
I am using Java Studio Enterprise 8's UML tool.
The modeling palette does not make provision for this type of association.
Is there a way to depict the ternary association icon, or is there an update for
the Modeling palette in the class diagrams?
It is the little diamond, looks the same as the decision icon."

Not sure if it's the same user, but here's another request.

Hi, is there a way to model ternary associations? (Put a diamond
between 3 classes) ?

I can't seem to find a way.
