SequenceBlockIdGenerator produces duplicate keys
------------------------------------------------
Key: JBPM-85
URL: http://jira.jboss.com/jira/browse/JBPM-85
Project: JBoss jBPM
Type: Bug
Versions: jBPM 2.0
Environment: jbpm 2.0, jboss 4.01, jdk1.5
Reporter: Armin Haaf
Assigned to: Tom Baeyens
SequenceBlockIdGenerator produces duplicate keys, if the transaction in which
the hilo block is read from the database is rollbacked. This could occur in a
j2ee environment in a jta transaction. IÂm not sure if a hibernate session
using jta transactions creates a new jta transaction, if a transaction is
already registered, but it seems it uses the current transaction. So the
beginTransaction, commit code in SequenceBlockIdGenerator did not commit
immediatly and could be rollbacked later.
