Jinchao,
For your second question, I think you can create multiple Child References
with each of them has a Node Mapping for different types, and set the
Compartment of all Child Reference to the same compartment mapping.

Hi Alex,
Thanks for responding to the question. I appreciate it very much.
My problem is that the GMF message is an error message, and the Next button
on the genration wizard is disabled.
In my ecore model the object to be displayed is owned by another model
object (with the containment set to true). To by-pass the error message, I
modified the ecore model so that the object to be displayed is owned by both
that owning object and the object that has the compartment. As a result, all
the objects created inside the compartment are persisted with the object
that has the compartment, not with the original owning object. I don't know
how to modify the generated code to switch the persistence to the original
owning object and create references inside the compartment object.
Thanks,
Jinchao
