Hi Henrique,
I am using a TemporaryEditingContext to test a group of related EOs. To try
and debug a test failure, I am saving the EC after the creation of each new EO.
At the point where I'm getting an IllegalArgumentException, the only new EO
inserted into the EC is a subclass by horizontal inheritance of a parent EO.
Inserting the subclass and saving throws this:
Caused by: java.lang.IllegalArgumentException: Attempt to insert null object
into an com.webobjects.foundation.NSMutableDictionary.

com.webobjects.foundation.NSMutableDictionary.setObjectForKey(NSMutableDictionary.java:68)

at er.extensions.eof.ERXEC._saveChanges(ERXEC.java:1110)
at er.extensions.eof.ERXEC.saveChanges(ERXEC.java:1032)
As noted, the only relevant difference I can see is the inheritance. Would you
expect the TemporaryEditingContext (or the memory adaptor) to have a problem
with (horizontal) inheritance?
