Problem while creating GMF models from xsd. [message #536101]

Hi All,
I am new to GMF. I have been trying to understand the concept of generating Ecore model from xsd.
I generated a Ecore model from xsd and used the same ecore file to generate genmodel. gen model created successfully.
But when i tried generating the "gmfgen" model out of genmodel.
It throws an error.

I need to know the following :
1.)Does GMF supports a Ecore model generated out of xsd.
2) I tried using Eugenia to generate gmfgen and gmf diagram from sample .emf model it works fine.But when i tried generating the ecore from "xsd" .It has some issues.
Does any body know how to go about it?
I got this error
Method 'getContainmentReferences' not found (190:38)

Hi,

Could you please confirm that you've added @gmf.xxx annotations to your metamodel as per http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-gmf- tutorial/?

Cheers,
Dimitris

Hi
Thanks for the response.
I was unable to find the link given.
I am trying to google out some of the samples to add GMF annotation to the the metamodel.I dint get it.
and
Should we always use emf instead xsd for Eugenia sample.?

Hi,

The forum parser apparently thought that '?' was part of the link. Here's the link again (without the '?'): http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-gmf- tutorial/

You don't necessarily need to use Emfatic to specify your Ecore model. If you already have a .ecore model from your .xsd you can open it and add the annotations using the tree-based Ecore editor.

Cheers,
Dimitris
