Seam 2 B1 - Ending a process instance fails.

Tomcat 6
Seam 2 B1
Jboss Embedded Beta 2

Signalling the last task on a process causes the following exception:

The code that raises the error is in: org.hibernate.transaction.JTATransaction.

public void registerSynchronization(Synchronization sync) throws HibernateException {
 if (getTransactionManager()==null) {
 throw new IllegalStateException("JTA TransactionManager not available");
 }
 else {
 try {
 getTransactionManager().getTransaction().registerSynchronization(sync);
 }
 catch (Exception e) {
 throw new TransactionException("could not register synchronization", e);
 }
 }
 }

So I guess the getTransaction() call is returning null.

Has anybody else had problems ending JBPM process instances in Seam2?

Obviously this all worked for me in 1.2.1GA.

What version of JBPM is used in Seam2? it's not 3.2.GA.

[jcruise]

built latest seam and jbpm-jpdl from cvs. Same problem.

Workaround is to disable the db scheduler service in jbpm.cfg.xml.

Cheers

It's a build from about 1 week before 3.2.1.GA was released I think (3.2.1.GA wasn't released in time for our BETA). Seam 2.0.0.CR1 should have 3.2.1.GA in.
