Hi Ed,
I did make the changes to the ecore model after I had already created
the GenModel (i.e. before regenerating over teh top of my existing
generated code), but I went into the GenModel in the editor afterwards
and checked that the "Edit/Children" and "Edit/Create Child" properties
of the features were set to "true".
By your question - I assume this should just "work" assuming I've set
the flags correctly?
Thanks,
Dan

ok apologies - somehow I'd managed to mess up the supertype hierarchy so
the type (MessageAction) with these references was missed out!
Looking much better now (in the generated code at least)
Many thanks for the help,
Dan
