Andrus Adamchik commented on CAY-1651:
--------------------------------------
Side effect of the new implementation - ObjectIdQuery with non-existing temp ID
will now execute successfully , but return no rows (in the past Cayenne stack
would throw)
> ObjectContext.localObject - defer FaultFailureExceptions on temporary IDs
> -------------------------------------------------------------------------

> ObjectContext.localObject(Persistent) created per CAY-1611 has a subtle
> difference with deprecated version of "localObject" - when passed a temporary
> ID, it does not blindly assumes this ID is valid, but rather tries to find it
> along the chain of parent contexts and throws immediately on failure. On the
> other hand we defer checking of permanent IDs, waiting for the user to access
> object properties outside 'localObject'.
> Permanent IDs can easily be invalid too (e.g. a DB row underneath can be
> deleted). Besides a valid ID can become invalid at any moment before or after
> localObject call. So a difference in handling both types of IDs is not
> logical. Let's defer temp ID checking, just like we do for perm ID.
