Oops! Spoke too soon. A google search for ObjectModifiedException pointed me to the
right spot in the FAQ. I had a lot of date fields mapped to Oracle DATE fields which
were probably the reason for this error. Th addition of dirty="ignore" did the trick.
Oddly, a search of the message archives did not yield anything. Thanks anyway.

Sunit,
which RDBMS are you using ? If you happen to be using mySQL, can you please post the
mapping for RemovalCandidate ?
Thanks
