Regression: Cayenne M9+ sets DataObjects as "modified" during no-op
writeProperties
-----------------------------------------------------------------------------------
Key: CAY-512
URL: http://issues.apache.org/cayenne/browse/CAY-512
Project: Cayenne
Type: Bug
Components: Cayenne Core Library
Versions: 1.2 [BETA]
Environment: M9-B1
Reporter: Mike Kienenberger
Fix For: 1.2 [BETA]
Regression: Cayenne M9+ sets DataObjects as "modified" during no-op
writeProperties
writeProperty("x", "y") puts dataObject into a modified state when "y" was
already the value of "x" before the method call.
Before M9, object would remain in committed state.
Object in my ObjectStore:
<ObjectId:Announcement, ANNOUNCEMENT_ID=200>={<ObjectId:Announcement,
ANNOUNCEMENT_ID=200>; modified; [enabled=>Y; description=>SNAP;
contentList=>(..); effectiveEndDate=>Mon Oct 31 00:00:00 EST 2005;
effectiveStartDate=>Thu Sep 01 00:00:00 EDT 2005;
qualifiedViewpointList=>(..)]}
ObjectDiff of record -- appears to indicate that nothing has changed.
Same as the other 4 restored objects.
Comparision of snapshot values to object store values shows nothing different.
value= ObjectDiff (id=3310)
arcSnapshot= HashMap (id=3311)
currentArcSnapshot= null
diffId= 1
flatIds= null
nodeId= ObjectId (id=3309)
objectStore= ObjectStore (id=3200)
otherDiffs= null
snapshot= HashMap (id=3312)

{enabled=Y, description=SNAP, effectiveEndDate=Mon Oct 31 00:00:00 EST
2005, effectiveStartDate=Thu Sep 01 00:00:00 EDT 2005}
A workaround has been to add code in my BaseDataObject class to check
for the old value equaling the new value in writeProperty(), and if
so, do nothing.
