Objects marked as modified with no changes?

[Mike Kienenberger <mk...@gmail.com>]

Is the new implementation of localObject incorrectly marking objects
as modified?  At this point in my app, all objects should be in the
committed state as all I've done is issue a request, fetch some
objects, serialize them, go to the next request, and restore them.

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)


org.objectstyle.cayenne.access.ObjectDiff@133d68a
{}
null

null
<ObjectId:Announcement, ANNOUNCEMENT_ID=200>
org.objectstyle.cayenne.access.ObjectStore@c0cf
null
{enabled=Y, description=SNAP, effectiveEndDate=Mon Oct 31 00:00:00 EST
2005, effectiveStartDate=Thu Sep 01 00:00:00 EDT 2005}

I'm going to try reverting back to M11.

Ok.   The problem started happening between M8 and M9.

Looks like a regression -- I'll open an issue.

I've hit this with M11, M10, and M9.  M8 is when the hsqldb switchover
occurred, so it's too much of a pain to test earlier versions right
now.

Turns out that JSF is automatically resetting DataObject properties
back to the same value they had before.  Now I'm pretty sure I wasn't
seeing this behavior in older versions of Cayenne.   I'll need to give
the M5 version a try again when I get a chance to verify.

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.
