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

Hi Jarda,

	Thanks for the hint! However, when I do not set the namespace of the
ActivityGraph, the ActivityGraph is not written in XMI file. In other words:
I do not receive the CompositionViolationException and the generated XMI
file correctly has an element relating the xmiid of the Operation with the
xmiid of the ActivityGraph, but the ActivityGraph itself is not there...

	The attached file (test.xml) is the generated XMI file. It is using
SPEM metamodel, but SPEM is derived from UML metamodel. The element
"SPEM:A_behavior_contex" relates a WorkDefinition, which extends Operation,
with an ActivityGraph (xmi.idref = "a7"). However, the ActivityGraph itself
(xmiid = "a7") is not there! Do you have any other hints?

	Thanks a lot!!!

	Leo
