[jbpm-issues] [JBoss JIRA] Updated: (JBPM-2818) Leaving node in super-state throws org.jbpm.JbpmException: cannot leave Node without leaving transition

Leaving node in super-state throws org.jbpm.JbpmException: cannot leave Node without leaving transition ------------------------------------------------------------------------------------------------------- Key: JBPM-2818 URL: https://jira.jboss.org/browse/JBPM-2818 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Documentation, Runtime Engine Affects Versions: jBPM 3.2.8 Reporter: Toshiya Kobayashi Assignee: Alejandro Guizar Fix For: jBPM 3.2.10 Attachments: JBPM-2818.patch Original Estimate: 0 minutes Remaining Estimate: 0 minutes Leaving <node> in <super-state> throws org.jbpm.JbpmException: cannot leave Node(node2) without leaving transition when I execute process definition like: ================ <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="id41"> <start-state name="start"> <transition to="super-state1"></transition> </start-state> <super-state name="super-state1"> <transition to="end"></transition> <node name="node1"> <transition to="node2"></transition> </node> <node name="node2"> </node> </super-state> <end-state name="end"> </end-state> </process-definition> ================= Note: <node name="node2"> doesn't have its own transition. but I expect super-state's transition is available then. The process definition works if you test via ProcessDefinition.parseXmlResource(String xmlResource) without DB/Hibernate (like org.jbpm.graph.exe.SuperStateActionExecutionTest.testNestedSuperStateLeaveViaSuperStateTransition()). What's the difference? org.jbpm.graph.def.Node: ========= public Transition getDefaultLeavingTransition() { Transition defaultTransition = null; if (leavingTransitions != null) { // Select the first unconditional transition for (Iterator i = leavingTransitions.iterator(); i.hasNext();) { Transition auxTransition = (Transition) i.next(); if (auxTransition.getCondition() == null) { defaultTransition = auxTransition; break; } } } else if (superState != null) { defaultTransition = superState.getDefaultLeavingTransition(); } return defaultTransition; } ========= The logic of getDefaultLeavingTransition() depends on whether leavingTransitions is null or not. But in case that hibernate kicks lazy initialization, leavingTransitions will be a zero sized collection, not null. BTW, I think the concept that super-state's transition can be chosen from nodes inside is better to be documented.
