[mdr-users] Operation as a context of ActivityGraph

Hello,

	I am using UML metamodel and trying to set the context of an
ActivityGraph to an Operation. The specification says the context of an
ActivityGraph may be a BehavioralFeature. Moreover, Operation inherits from
BehavioralFeature. However, a CompositionViolationException is thrown. It
complains that I am trying to set more than one context to the
ActivityGraph. I suppose it considers the namespace where the ActivityGraph
is inserted as an existing context. Am I doing something wrong? What is the
correct way to set the context of an ActivityGraph to an Operation? Where
should I insert the ActivityGraph to avoid the
CompositionViolationException?

	Thanks,

	Leo
