UML Pattern & Sequence Diagram

[fbe]

Is it possible to generate a UML Pattern in EA from a sequence diagram? I have a sequence diagram which I want to use as a base. I can create the UML pattern from the diagram and select classes to add/rename etc. but when that is done, all the messages are gone. I would like the messages to stick around also. Any ideas?

From EA Help:

Patterns are parameterized collaborations - that is they are a group of collaborating objects/classes that can be abstracted from a general set of modeling scenarios

so perhaps only collaborations are saved 'properly' as patterns ...?

Though I would have thought a Pattern should be applicable to any suitably parameterisable model diagram.

I am guessing that the 'dynamic' elements (messages) are lost, in this case.
