Re: Strange error

That method gets called for all entities, not just read only ones.  The check 
for being read-only is inside the method.

Some state inside EOF is messed up.  Are you doing anything with database 
operations in your app?  Or it could be concurrency and unlocked EOF access 
that is scrambling the state.  What changed before this started?

You probably need to figure out what is on line 4700, and what might be null 
and work back from there.

Hi Michael,

It appears one of the objects being saved is for a read only entity.  Can you 
tell if that is what is going on?

Would any one know what is causing it?
