Hi, I've been using Seam 2.0.0.GA with jBPM 3.2.2 and have run into some issues with executing timer tasks.
I have a simple process with a timer: | <?xml version="1.0" encoding="UTF-8"?> | <process-definition xmlns="urn:jbpm.org:jpdl-3.1" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; | xsi:schemaLocation="urn:jbpm.org:jpdl-3.1 http://jbpm.org/jpdl-3.1.xsd"; | name="timerTest"> | | <start-state name="start"> | <transition name="" to="timerTest" /> | </start-state> | | <task-node name="timerTest" end-tasks="true"> | <event type="node-enter"> | <action expression="#{timerTestWorkflow.logNodeEnter}" /> | </event> | <event type="node-leave"> | <action expression="#{timerTestWorkflow.logNodeLeave}" /> | </event> | | <task name="timerTestTask" description="TimerTestTask"> | <assignment actor-id="admin" /> | <event type="task-create"> | <action expression="#{timerTestWorkflow.logTaskCreate}" /> | </event> | | | <event type="timer-create"> | <action expression="#{timerTestWorkflow.logTimerCreate}" /> | </event> | <timer duedate="15 seconds" transition="finished"> | <action expression="#{timerTestWorkflow.logTimerFired}" /> | </timer> | | </task> | <transition name="finished" to="end" /> | </task-node> | <end-state name="end"></end-state> | </process-definition> | However, when the timer fires and the process instance is ending I receive the following error in the logs: | 2008-02-04 14:42:16,419 DEBUG
