Try to create "phantom" node mappings for these child nodes. This means:
-	create a TopNodeReference with appropriate NodeMapping for each of child 
nodes
-	leave âcontainmentFeatureâ property of these TopNodeReferences empty (this 
means corresponding top nodes will not be stored inside diagram domain element 
hierarchy on creation)
-	create Link mappings using containment reference from child nodes container 
(located in a compartment) to these child nodes
As a result you will have the situation then you can create âphantomâ child 
nodes on diagram (corresponding domain model elements will be stored in a 
root of EMF resource) and then link these nodes with their parent element 
located inside a compartment using special link (in this moment corresponding 
domain model element will be moved below the actual parent, but visually 
will stay on the same place).
