Description William Piers

2010-09-27 11:44:57 EDT

Steps to reproduce:
- create an ecore model, eef model and so on
- modify the ecore model, e.g. delete an EAttribute which is used by the EEF model
- edit the EEF model to re-assign the invalid view (i.e. the one related to the deleted feature) to another feature
=> the EEF editor throws the error below, and modifications are no longer savables

Workaround:
Open the eef model using EMF's reflective editor.

The Eclipse EEF team has worked over the past few months on a brand new runtime using a reflective approach which can be used more easily with Eclipse Sirius. Since we do not plan to continue to work on the old runtime and its code generation approach, I will close this issue for now.

If you want to contribute, you can reopen this issue and submit a contribution to the project thanks to our Gerrit: https://git.eclipse.org/r/#/admin/projects/eef/org.eclipse.eef
