Genmodel Changes and XMI Resource [message #658505]

Hi,

We are using EMF in our project and facing some problems with genmodel changes and XMI Rresource.

e.g I have an EObject with attributes 'name' and 'description'. I create the object and save it as xmi resource.

Now if for some reason i have to change the model and remove attribute 'name', xmi resource is no longer usable as it does not comply with latest model definition.

What can be done in these cases?

Any suggestion?

It will throw exceptions while loading, but the resource as a whole
still loads properly...
