问题
I'm looking for an example of an activity diagram where one action is a Call Operation Action and is calling another action with more than one parameter being passed.
I have search quite a few uml books, search online and gone through the uml2 specification but cannot find an example representing the above.
This question is similar to my previous question, but is much more specific hence I don't think it is a duplicate question.

I don't have the rights to post examples of my own work, but you can see Conrad Bock's excellent series of articles. In section 4 of column 4 of the series, he has examples of exactly what you're looking for. I don't have the fUML spec handy, but I remember seeing many unit tests that taught me a lot about activity diagram token semantics. Those were eye opening! I can't remember whether these tests were in the spec or in Ed Seidewitz's open-source fUML implementation.
