Condition in transition not retrieved from database JBPM_TRANSITIONS#DECISION_ ------------------------------------------------------------------------------ Key: JBPM-854 URL: http://jira.jboss.com/jira/browse/JBPM-854 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2 beta 2 Environment: All Reporter: Arjan van Bentem Assigned To: Tom Baeyens Though table JBPM_DECISIONCONDITION is replaced by column DECISION_ in table JBPM_TRANSITIONS, the Java code will still query that old table to load processes that were deployed using a previous version. For an empty query result Hibernate will return an empty List (at least for the Hypersonic database), while the code only checks for the List to be null. This fails, and results in conditions not being taken from JBPM_TRANSITIONS. Fix: replace line 105 of Decision.java (version 1.3) http://fisheye.jboss.com/browse/JBPM/jbpm.3/jpdl/jar/src/main/java/org/jb... 48 List decisionConditions = null; : 105 } else if (decisionConditions!=null) { 106 // backwards compatible mode based on separate DecisionCondition with 105 } else if (decisionConditions!=null && !decisionConditions.isEmpty()) { To test one could replace org.jbpm.graph.node.JpdlDbTest#testDecision() to use correct EL expression, and then signal the process to invoke the troublesome code: http://fisheye.jboss.com/browse/JBPM/jbpm.3/jpdl/jar/src/test/java/org/jb... public void testDecision(){ ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( "<process-definition>" + " <start-state>" + " <transition to='d' />" + " </start-state>" + " <decision name='d'>" + " <transition name='one' to='a'>" + " <condition>#{a == 1}</condition>" + " </transition>" + " <transition name='two' to='b'>" + " <condition>#{a == 2}</condition>" + " </transition>" + " <transition name='three' to='c'>" + " <condition>#{a == 3}</condition>" + " </transition>" + " </decision>" + " <state name='a' />" + " <state name='b' />" + " <state name='c' />" + "</process-definition>"); processDefinition = saveAndReload(processDefinition); Decision decision = (Decision) processDefinition.getNode("d"); assertEquals("#{a == 1}", decision.getLeavingTransition("one").getCondition()); assertEquals("#{a == 2}", decision.getLeavingTransition("two").getCondition()); assertEquals("#{a == 3}", decision.getLeavingTransition("three").getCondition()); // Assure org.jbpm.graph.node.Decision#execute gets the conditions from // table JBPM_TRANSITIONS rather than the obsolete JBPM_DECISIONCONDITION: ProcessInstance processInstance = new ProcessInstance(processDefinition); processInstance.getContextInstance().setVariable("a", new Integer(2)); processInstance.signal(); assertEquals(processDefinition.getNode("b"), processInstance.getRootToken().getNode()); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
