Could it be that you exposed the foreign key that you use for the
relationship (stateID)? I think that if you do that and do not set it
up by hand, you end up with a null pointer exception for the key.

Hi Chuck,
The state relationship is not checked to Owns Destination. I logged
the insertedObjects and it only contains the client.
Any clues?

Did you mark the Client's state relationship as Owns Destination in
the
model? If so, EOF is creating a blank State when you create a new
client.
Try logging out client().editingContext().insertedObjects() before
the call
to saveChanges().

I have just started to make a small application and have come across
a problem that won't seem to go away.
I have 2 entities, State and Client, when I create a new client and
select the state they live in, when I go to save the changes I get
the following error.
EditClient (EditClient.java:48) -
<er.extensions.ERXValidationException object: <davinci.Client
pk:"null">; propertyKey: stateID; type: NullPropertyException;
additionalExceptions: ()>
The state popup's selection property is set to the clients state
relationship. It is all in a form so I don't know why it is getting
set as null. All the other properties of form are correct, including
another to one relationship on the client.
Does anyone have any clues as to why this would be occuring?
Any help is greatly appreciated.
Regards,
Greg
