[News.eclipse.technology.gmf] show non containment features in a compart

["Anabela Monteiro" <aspm@xxxxxxxxxxxxx>]

Hi,

We are developing an activity diagram using the uml2 plugin.
In the UML model the element Activity (ower root) is the container of 
ActivityNodes, ActivityEdges and ActivityPartitions. Partitions only have 
references to ActivityNodes and ActivityEdges but it´s not a container of 
those elements. In ower diagram, we wanna be able to put nodes and eges 
inside a partition. We try to define compartments inside the 
ActivityPartition node but the problem is we can´t define the containment 
feature in the child reference, because the ActivityPartition element has 
the EReference node and edge with the property containment set to false.

So my question is, how can we show non containment features in a 
compartment?

Can you help me?
Thanks in advance,

Anabela
