Investigated further: 1) With jbpm.loadToken instead of jbpm.loadTokenForUpdate it works 2) Using jbpmContext.newProcessInstanceForUpdate("Test") also causes the exception. So my guess is, that the registered autoSave somehow messes in combination with the deletaion. So my next try was to start a new transaction before deleting, and I get a green bar again: | ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(xml); | jbpmContext.deployProcessDefinition(processDefinition); | | ProcessInstance processInstance = jbpmContext.newProcessInstanceForUpdate("Test"); | // ProcessInstance processInstance = processDefinition.createProcessInstance(); | Token token = jbpmContext.loadTokenForUpdate(processInstance.getRootToken().getId()); | | newTransaction(); | | jbpmContext.getGraphSession().deleteProcessDefinition(processDefinition.getId()); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4195493#...
