[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: help with optimistic locking

[balamg]

Furhter debugging resulted in this observation:

in other than lockmode=write, the transaction gets committed.

in the lockmode=write, this is what is happening:

java.lang.NullPointerException

2006-08-01 13:34:58,765 ERROR [STDERR] 	at org.jboss.ejb3.entity.TransactionScopedEntityManager.lock(TransactionScopedEntityManager.java:101)

any known workarounds ? fixes  ? patches or is it a wrong usage ?

Thank You
