overriding setPersistentState() in unreliable in three tier environment with
CayenneContext
-------------------------------------------------------------------------------------------
Key: CAY-653
URL: http://issues.apache.org/cayenne/browse/CAY-653
Project: Cayenne
Type: Bug
Components: Cayenne Core Library
Versions: 1.2 [STABLE]
Reporter: Ari Maniatis
After looking at the source for CayenneContext.newObject (and non-public
CayenneContext.createNewObject) it seems that overriding setPersistentState (as
suggested:
http://cwiki.apache.org/confluence/display/CAY/Setting+Initial+Values) is a bad
idea, esp for new objects. i.e., at the point of being NEW the object's
ValueHolder vars have not yet been initiated, it doesn't yet have a handle on
the context, it's global id has not been set, and it's not been registered with
the graph manager etc. Simply put, bad stuff happens when messing with the
objects ValueHolder vars prior to all of this.
Perhaps a delegate such as EOF's awakeFromInsertion() would be ideal. This
would hook in as the very last thing CayenneContext.createNewObject() does
before returning and would avoid users having to subclass the context.
