CayenneContext.rollbackChanges (client-side) is marking objects in other
contexts as transient!
-----------------------------------------------------------------------------------------------
Key: CAY-771
URL: https://issues.apache.org/cayenne/browse/CAY-771
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Environment: Mac OS X 10.4.9, Java 1.5, Cayenne 3.0-prerelease svn
515808
Reporter: Lachlan Deck
Assigned To: Andrus Adamchik
The problem is: (this is 3 tier client-side)
- having two edit screens open, each with their own editing context but editing
the same type of object
- use one edit screen and enter some data (particular data that sets a
relationship value)
- close the edit screen where you've adjusted the data and then attempt to
repeat the steps in the other edit screen.
- Exception thrown because the object you're trying to set the relationship on
no longer has a context!
-------------------------------------------
--- logging and stack traces -----
-------------------------------------------
The context rolling back changes: (our subclass is simply calling super)

rollbackChanges:[EMAIL PROTECTED]
Here's a stack trace from setPersistenceState; in our PersistentObject subclass
I'm just logging (before calling super) the object. Notice this particular
object is in a different context - but it's being marked as transient :-/
---- Here's the relevant stack trace from setPersistenceState in the object
that shouldn't be touched -----
