1. Create a metamodel that has a class with reference to another class where containment = false.
2. Generate all.
3. Change containment to be true
4. Optionally use the "clean generated..." feature to show that even that doesn't fix the problem.  I believe even deleting the meta-class and re-creating it with the same name doesn't fix it.  I think the only workaround is to create the reference with a new name.
5. Generate all.
4. Open the editor and verify that the editor ignores the containment=true and that you cannot right-click to create new objects.

This is working as designed. I.e., the GenModel preserves all settings.  When it's initialized/created, it bases many settings on the state of the model at that time.  I.e., containment references have their GenFeature's Children property set to true.  But under no circumstance is a property changed during reloading.  You have to do that explicitly yourself, i.e., by changing the properties for the GenFeature.
