EMF Cross Reference : Resolve eProxy ? [message #1048201]

I have a Ecore with a cross reference to an other Ecore. I use ODA Driver with OCL request to access datas of Ecore instance.

I can't access to Ecore EClass of a cross reference. When my OCL request must return a referenced type, I can't specify result type because other Ecore types didn't appear in choices dialog.

Other problem is that returned Java Object is an EMF Proxy and I can't use it without resolve it before.

How can I resolve cross Reference in DataSet ?

Gabriel,

The general cause of proxies failing to resolve is not loading the
initial resource with an absolute URI, e.g., if it's from the file
system, you should use something line file:/c:/path/file.xtension.

Thank's Ed,

Indeed to solve this problem, I changed resource loading. Your answer confirms the good practices to load a resource.
