I am seeing a strange issue in my jbpm 5 + hibernate + mysql configuration.
A test process 'com.sample.bpmn' consists of the following: start ->
myactivityhandler -> somescript -> end
myactivityhandler is an async activity handler and hence 'execute' returns without
calling completeWorkItem.
Now after execution of the following snippet:
..
ksession.startProcess("com.sample.bpmn");
..
I look at the ProcessInstanceInfo for the process and I see that the instance state is
rightful set to ACTIVE since the process is actually active and just hit its first
savepoint after the myactivityhandler.
However if I break the startprocess down to the following:
..
ProcessInstance pi = ksession.createProcessInstance("com.sample.bpmn", null);
ksession.startProcessInstance(pi.getId());
..
After execution of the above two, I expect the state would be the same as the previous
snippet i.e. process instance state == ACTIVE but in reality it is set to PENDING. Also
when I trace the SQL that hibernate is sending to MySQL I don't see any UPDATE going
to the ProcessInstanceInfo table. This is a problem since now I can't complete the
myactivityhandler workitem to continue the process.. and it needs to be started again.
Any clue why the above two scenarios are behaving differently?
Fwiw, if I configure the system to use the in-memory H2 then everything works fine and
dandy.
Thanks

A had a similar problem.
*My setup is:* JBPM 5.2.0 + JPA + Hibernate + java:jboss/TransactionManager + MSSQL +
JBoss AS 7
I'm using WI handlers in similar way - some are synchronous and some are asynchronous,
but state of process wasn't persisted correctly in save points (at the end of
execution of WI handler). I found that my transaction manager didn't work correctly
and all process instances stay all the time in memmory and wasn't loaded/inserted into
DB. Problem was that my transaction manager wasn't added into Environment.
You can easy forget for this very important step in your code. Everything seems working
correctly if you are not restarting jBPM and you don't need any recovery utility. I
was looking into manual about transactions here:
http://docs.jboss.org/jbpm/v5.2/userguide/ch07.html#d0e2914
http://docs.jboss.org/jbpm/v5.2/userguide/ch07.html#d0e2914 I also read source code of
jbpm-gwt-console (class CommandDelegate) but there is now direct description how to
configure and use JBoss transaction manager. Maybe small update of manual should by
helpfull.
*Solution:*
Maybe this help someone with similar issue. Correct codes:
Configuration of transaction manager for JBoss AS 7 in persistence.xml:
<property name="hibernate.transaction.manager_lookup_class"
value="org.jbpm.integration.console.JBPMTransactionManager" />
Do not forget for this during initialization of your sessions, environment ... for
example:
// get transaction manager from hibernate configuration (see persistence.xml)
TransactionManagerLookup transactionManagerLookup =
((SessionFactoryImplementor)((HibernateEntityManagerFactory)emf).getSessionFactory()).getSettings().getTransactionManagerLookup();
TransactionManager transactionManager =
transactionManagerLookup.getTransactionManager(null);
// this is very important step to add transactionManager into env. Else transaction
manager will not be initialized correctly for jbpm.
*env.set(EnvironmentName.TRANSACTION_MANAGER, transactionManager);*
Working for me correctly now.

Yes that was exactly my problem as well. Now I feel guilty for not updating this thread
when I found the issue :)
Thanks!
