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)

Following is the StackTrace ::

<er.ajax.AjaxRequestHandler>: Exception occurred while handling request:
java.lang.NullPointerException
 <WorkerThread11> java.lang.NullPointerException

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

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