Hi,

We are getting NullPointerException while setting the values to the flattened relationship.

Actually, we have created flattened relationship between two entities, which are present in two different EOModels . (different DBs also)

I am pretty sure that you can't flatten in this situation.

* same code is working, if both entities are in same EOModel.

Please let me know if there is any other configurations/changes.
