[jboss-user] [JBoss jBPM] - jBPM 3.3.0GA and Oracle causing StaleObjectStateException

[xnejp03]

Hi guys,

I've upgraded from 3.2.3 to 3.3.0.GA (Oracle) and getting this exception after creating a process instance :

Caused by: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.graph.exe.Token#3591]

I found this issue: https://jira.jboss.org/jira/browse/JBPM-1772 which looks like a flush() has been removed which previously fixed an Oracle bug. Could this be the problem?

Cheers,

Petr
