Hello, There are some new methods introduced in FAMIXBehaviouralEntity: clientBehaviours and providerBehaviours. clientBehaviours <MSEProperty: #clientBehaviours type: #FAMIXBehaviouralEntity> <multivalued> <derived> <MSEComment: 'All behaviours that depend on the receiver'> ^ self invokingMethods InvokingMethods is defined in one of the subclasses of FAMIXBehaviouralEntity: FAMIXMethod and not the other subclass, FAMIXFunction. I have my code that subclasses FAMIXFunction and when I try to export the object to an MSE, there is an error: MyFunction(Object)>>doesNotUnderstand: #invokingMethods. So, IMO, clientBehaviours and providerBehaviours methods need to point to a method at the same level instead of sending message to a subclass method. regards, Usman _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
