<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've strange problem with spring and jbpm. I have code which works sth like that:</p><p>Session session = sessionFactory.getCurrentSession();</p><p>Order order = new Order();</p><p>ExecutionImpl e = processEngine.startProcess(order);</p><p>log(e.getId());   //this logs new process id from jbpm4_execution table, let's say id = 1000</p><p>order.setProcess(e);</p><p>session.save(order);</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>order entity has a foreign key to the process it's connected to.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>on saving order in last line I have error from DB the process with id = 1000 does not exist.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I debug jbpm and dig into RepositorySessionImpl - it has hibernate session object encapsulated and it's different than 'my' session object.</p><p>But they both have the same SessionFactory object (the same hashcode etc).</p><p style="min-height: 8pt;
