When trying to insert an entity into the database as in



I get the following exception:
Expected: class java.lang.Integer, got class org.hibernate.action.DelayedPostInsert Identifier

This only happens if doing the add is the first thing I do on a page. If I edit a db object or delete one before adding, everything seems to work fine.

I am running this under JBoss Seam. I did try asking the same question on the JBoss seam forums, but got no response so I figured I'd try here.

Any ideas or pointers on how to correct/investigate this?

Didn't mention this initially, but the insert does occur and a new row is entered into the database.
