XSD to EMF [message #580376]

Hi all,

I followed this tutorial ( http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. emf.doc/tutorials/xlibmod/xlibmod.html) to create an EMF model from an XSD. I didn't want a custom editor or anything so stopped after that.

I have my ecore file sitting happily in my project and I register the EPackage, which works fine. I then create an Epsilon EMF Model from the wizard, choosing my newly registered EPackage as the metamodel uri. The model file is created fine, and I can add the expected elements into the model. However, these elements do not persist once the file is closed and reopened - leaving just the root node and no child nodes.

Creating a model instance of a pre-registered metamodel (such as UML2) works fine. Is there possibly something wrong with the way the XSD is transformed. Maybe this should go into the EMF forum?

The XSD is here: http://czt.sourceforge.net/zml/zml/Z_2_1.xsd

Cheers,

James

Hi James,

This may be an issue related to Exeed. Could you please name your model
..xmi or .ecore and try to edit it with the built-in reflective editor
and let me know what happens?

Cheers,
Dimitris
