[jbpm-issues] [JBoss JIRA] Assigned: (JBPM-2834) Conditional transition cannot be considered as a default one

Conditional transition cannot be considered as a default one ------------------------------------------------------------ Key: JBPM-2834 URL: https://jira.jboss.org/jira/browse/JBPM-2834 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.8, jBPM 3.2.9 Environment: SOA-P 4.3.CP03 ER1 Reporter: Martin Vecera Assignee: Alejandro Guizar The documentation reads: ==== The contents of the condition element is a jPDL expression that should evaluate to a boolean. A decision takes the first transition (as ordered in the processdefinition.xml) for which the expression resolves to true. If none of the conditions resolve to true, the default leaving transition (== the first one) will be taken. ==== If I have only a conditional transition in a node (hence the first one) it is not used as the default leaving transition. Process definition to simulate the behaviour: ==== <?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="processDefinition3"> <start-state name="start"> <transition to="node1"></transition> </start-state> <node name="node1" async="true"> <transition to="node2" condition="#{AAA == null}"></transition> </node> <node name="node2"> <transition to="end1"></transition> </node> <end-state name="end1"></end-state> </process-definition> ==== Exception being thrown on signaling process's token: 10:16:33,629 ERROR [JobExecutorThread] job execution failure org.jbpm.JbpmException: transition is null at org.jbpm.graph.def.Node.leave(Node.java:449) at org.jbpm.graph.def.Node.leave(Node.java:430) at org.jbpm.graph.def.Node.execute(Node.java:421) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:173) at org.jbpm.graph.def.Node_$$_javassist_81.execute(Node_$$_javassist_81.java) at org.jbpm.job.ExecuteNodeJob.execute(ExecuteNodeJob.java:24) at org.jbpm.job.executor.JobExecutorThread.executeJob(JobExecutorThread.java:192) at org.jbpm.job.executor.JobExecutorThread.run(JobExecutorThread.java:66) JBPM-Console says: Error signalling token: An exception of type "org.jbpm.JbpmException" was thrown.
