JBoss 3.2.4/5 handling of null CMP fields
I am trying to migrate an applcation from 3.2.3 to 3.2.4/5. The application has been running in 3.2.3 for several months with no problems. I am now having a problem with any CMP fields containing null values. When retreiving the value object, I'm getting an error like this:
javax.ejb.TransactionRolledbackLocalException: Internal error getting results for field instructions; CausedByException is:
null; CausedByException is:

Here's another piece of the stack trace:
