Steven,
1. Yes, generally you create a root model class to aggregate the classes in
you model which you want to structure in a tree. See the library tutorial,
for example.
2. Yes. If you don't, you'll need to do a lot of hand customization to the
generated code.
In the future, please post these kinds of questions to the emf newsgroup,
instead of this mailing list.
Thanks,
Frank.

Dear all
I'm creating a meta model using Rose, and using EMF to generate the default
editor. I met two problems:
1. Do I need to create a root meta class in the rose model, whose instance
will be the root for all the elements in the instance model created using
the generated editor? If there's no such a root meta class, then the
elements created in the instance model can not be organized in a tree, and
can not be connected with one another.
2. Do I need to connect 'parent' meta class and 'child' meta class using
Aggregation, in the meta model? If no, then in the generated editor, there
will be no Context Menu Item of the 'parent' meta class instance to create
instances of the 'child' meta class.
Thanks!
Best Regards,
Steven
