[jira] [Created] (CAY-1651) ObjectContext.localObject - defer
FaultFailureExceptions on temporary IDs
ObjectContext.localObject - defer FaultFailureExceptions on temporary IDs
-------------------------------------------------------------------------
Key: CAY-1651
URL: https://issues.apache.org/jira/browse/CAY-1651
Project: Cayenne
Issue Type: Improvement
Components: Core Library
Affects Versions: 3.1M3
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Priority: Minor
Fix For: 3.1M4
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.

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)
