How do I remove en entity from the PM cache when the entity is in an added rowstate?
I end up with a RowNotInTableException.

It is likely that you actually have removed the entity from the cache, but you are getting an exception because somewhere in your application you still have a reference to the deleted entity.  Be especially careful that the deleted entity has been deleted from all EntityLists before you try to delete the entity.

Thanks for your quick reply,
The solution was to remove my subscription to the PropertyChanged event.

Japal.
 
Congratulations.  I was going to add that the problem was not likely to caused by a reference in an EntityList because in V3, references to deleted entities are automatically removed by DevForce unless you’ve explicitly set the ShouldRemoveDeletedEntities property on the EntityList to false (it defaults to true).
