Support for multiplicity on operation parameters

[ckesselh]

Hello everybody!

According to the UML 2.1 Infrastructure Specification, Parameters for Class Operation's should (on the meta-model-level) inherit from MultiplicityElement and thus support the isOrdered, isUnique, lower and upper attributes on each instance of that meta-class.

Although other UML2 implementations (such as the Eclipse UML2 EMF model) seem to comply with the specification in that respect, I myself can't find a way to do something similar in Enterprise Architect - that is e.g. specify a lower/upper bound on an operation's parameter via the application's existing graphical user-interface. I find this to be rather inconsistent, especially since multiplicity seems to be correctly supported on other UML meta-classes that extend MultiplicityElement in much the same way, such as Property.

Also, this gives me some trouble for my openArchitectureWare-based MDA-transformations, as I e.g. need to create a XXXList resp. XXXSet class for every other class XXX from my model that I want to support as a parameter of another class operation (with >1 instance of XXX being passed-in at the same time).

Am I missing something, here?

Thanks in advance,

Chris

Hi Chris,
although this is far to special for me to answer: if you can refer the section in superstructures then you could send a bug report to Sparx.

Would be nice to update this thread with responses later on.
