Re: [mdr-users] Operation as a context of ActivityGraph

Hello Leo,
You can't set the composition more than once. That's the reason why all compositions defined by UML (ModelElement in Namespace, Feature in Classifier...) are optional (multiplicity is 0..1). So if you want to specify ActivityGraph for some BehaviorFeature you mustn't specify its namespace (if it has been already set you must first set it to null).
