I tried what you suggested me, but it did not work.
I finally could solve my problems with transient object exception, saving
explicitly through Hibernate Session:
jbpmContext.getSession().save(executionContext.getTaskMgmtInstance());
or
jbpmContext.getSession().save(contextInstance);
thanks for reporting back...

Does the TaskNode.addTask(task) method works well?
I'm printing my process definition to check if is well builded and everything
appears well excepts the tasks that don't appear!
Any idea why they don't appear? Probably this is why is not working
programmatically and yes with the xml defintion
why do you create a new context in the actionhandler?
and with TaskNode.addTask you change the processdefinition, not adding
additional tasks to the running instance

Hi all,
Although the lock=UPGRADE without the session.flush() solves the problem
in 3.3.0.GA, the same solution in version 3.2.3 does not work.
For our company this is not a problem, we can switch to 3.3.0.GA easily since
we do not run production right now.
I thought this was valuable

To All,
Specifying the lock=UPGRADE on the join node does the trick!!
Even without the call to session.flush() in the join class.
I want to thank all of you for your great support!!!
Hopefully the fix for this bug can be included in the next release.
Thanks again!

We are having the same problem. Has anyone tried other options like
optimistic-lock=false
on some of the relationships between token and the other tables? The children
relationship looks suspect in that is a child Token gets removed or added, the
version of the parent Token is incremented.

oracle (the real ones and not just h2 in the different modes to be sure), and

Martin,
I did a similar test with 3.3.0 and run it against HSQLDB, H2 and mysql with

unit test so we are sure we use the same test?
View the original post :
if I only had a unit test... sigh... the lack of a proper test is probably the
reason why the failure was reintroduced in 3.3.0.
I'm pretty convinced this issue only shows on certain dbs, such as Oracle and
Postgres. I can give it another try on MySQL, too (and then write a proper test
;-) )
Martin... I found a similarity Oracle and Postgress use sequences, mysql,
h2 and hsqldb use auto-increment like id's. I've seen that postgress can also
support auto-increment if the int8 is changed to 'serial', see
H2 is cl. it has an oracle and postgress compatible mode If
you use it's own H2 driver, but point to a Oracle dialect and state in the

What is your isolation level? And could you create a minimal unittest like I
