Hi,
I have created an EMF Project,and defined an ecore model. I then created
an EMF Model of this ecore model (using 'Load from an EMF core model
option and generated code for it (.edit,.editor).
In the 'Runtime Workbench' I have used the model editor to create an
instance model.
If no association (EReference) is defined as containment, no 'child
objects' are allowed to be created.(On right click 'New Child' option does
not appear)
Does EMF not allow creating multiple top level entities ?
Thanks
Arti

Arti,
EMF has no built-in support for creating new children directly as the
root of the resource. Multiple roots are really only supported for XMI
serialization where a "fake" root XMI element is serialized to produce a
valid XML result. Since any object can be a root, there's really no
restrictive list of choices we could offer generically.
