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:

I have posted on the seam forums, but it was suggested that I try on this forum for any
further ideas.
seam forum: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=123558
I have also filed a seam jira with a full description and test code, available at:
http://jira.jboss.org/jira/browse/JBSEAM-2575
Any thoughts or suggestions on this issue would be gratefully received.
Many thanks, Peter.
