[JBoss JIRA] Created: (JBPM-1102) Despite source comment, JobExecutorServlet does not stop threads on destroy

by Pierre Demeestere (JIRA)

Despite source comment, JobExecutorServlet does not stop threads on destroy --------------------------------------------------------------------------- Key: JBPM-1102 URL: http://jira.jboss.com/jira/browse/JBPM-1102 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: Windows NT and Linux RH 4 Reporter: Pierre Demeestere Assigned To: Tom Baeyens Priority: Minor when stopping application server, an NullPointerException is spoted at line 84 for JobExecutorThread. That maybe because threads are not stopped properly when the JobExecutorServlet is undeployed. Indeed, despite source comments in JobExecutorServlet, nothing is done in this servlet to stop the threads when the servlet is undeployed. -- 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

[JBoss JIRA] Created: (JBPM-1093) Allow more than one action to be executed when entering a page node

by Matthew Lieder (JIRA)

Allow more than one action to be executed when entering a page node ------------------------------------------------------------------- Key: JBPM-1093 URL: http://jira.jboss.com/jira/browse/JBPM-1093 Project: JBoss jBPM Issue Type: Feature Request Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Reporter: Matthew Lieder Assigned To: Tom Baeyens Only the first <action> is executed when multiple actions are children of <page> and <start-page> elements in a jPDL pageflow. It would be greatly appreciated if the logic could be changed so that all <action> elements are executed (like they are when children of <transition> elements). Example: <page name="page1" view-id="/page1.xhtml"> <action expression="#{someMethodThatIsExecuted} /> <action expression="#{someMethodThatIsNotExecuted} /> <transition name="save" to="terminate"> <action expression="#{someMethodThatIsExecuted} /> <action expression="#{someMethodThatIsExecuted} /> </transition> </page> -- 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

[JBoss JIRA] Created: (JBPM-1173) Fork Node doesn't support conditions on Transitions

by Britt Miner (JIRA)

Fork Node doesn't support conditions on Transitions --------------------------------------------------- Key: JBPM-1173 URL: http://jira.jboss.com/jira/browse/JBPM-1173 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2 Reporter: Britt Miner Assigned To: Tom Baeyens Documentation does not clearly provide any limits to where conditions on Transitions can be used, but the Fork Node doesn't support Transition conditions. For instance <fork name='FORK_1' > <transition name='t1' to='NODE_A'> <condition>#{false}</condition> </transition> <transition name='t2' to='NODE_B'/> </fork> will fail with a "transition condition #{false} evaluated to 'false'" error when the fork attempts to take transition 't1'. Why provide for this? Someone might want to: <fork name='FORK_1' > <transition name='startMyProject' to='...'/> <transition name='orderEngine to='...'> <condition>#{needsEngine}</condition> </transition> <transition name='orderWheels to='...'> <condition>#{needsWheels}</condition> </transition> ...etc... </fork> Correcting the issue is as simple as making the following change to org.jbpm.graph.node.Fork.java: // BRITT --replace the following line with the code below // to check conditions before adding valid transitions... //transitionNames = getLeavingTransitionsMap().keySet(); //original line Iterator iter = leavingTransitions.iterator(); while (iter.hasNext()) { Transition candidate = (Transition) iter.next(); String conditionExpression = candidate.getCondition(); if (conditionExpression != null) { Object result = JbpmExpressionEvaluator.evaluate(conditionExpression, executionContext); if (Boolean.TRUE.equals(result)) { transitionNames.add(candidate.getName()); } }else{ transitionNames.add(candidate.getName()); } } if (transitionNames.size() == 0) { transitionNames.add(this.getDefaultLeavingTransition().getName()); this.getDefaultLeavingTransition().removeConditionEnforcement(); log.warn("All transition conditions have evaluated to 'false'. Taking the default transition."); } // --BRITT -- 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
