[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2817) Repeat Timer Issue

Repeat Timer Issue ------------------ Key: JBPM-2817 URL: https://jira.jboss.org/jira/browse/JBPM-2817 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0 Environment: Spring 3.0 JDK 1.6 Reporter: Sean Mo Assignee: Huisheng Xu Fix For: jBPM 4.4 This happened on jBPM 4.0. Initially I defined a normal timer in my process definition, it worked well but after I changed it to a repeat timer (by adding repeat="30 seconds"), I encountered the following exception: Mar 4, 2010 5:40:35 PM org.jbpm.internal.log.Jdk14Log error SEVERE: exception while executing 'timer[23|2010-03-04 17:41:05,391|TimeoutEvent]' org.jbpm.api.JbpmException: no transaction in environment at org.jbpm.pvm.internal.job.TimerImpl.execute(TimerImpl.java:150) at org.jbpm.pvm.internal.job.TimerImpl.execute(TimerImpl.java:52) at org.jbpm.pvm.internal.cmd.ExecuteJobCmd.execute(ExecuteJobCmd.java:74) at org.jbpm.pvm.internal.cmd.ExecuteJobCmd.execute(ExecuteJobCmd.java:41) at org.jbpm.pvm.internal.svc.DefaultCommandService.execute(DefaultCommandService.java:42) at org.jbpm.pvm.internal.spring.CommandTransactionCallback.doInTransaction(CommandTransactionCallback.java:50) at org.springframework.transaction.support.TransactionTemplate.execute(TransactionTemplate.java:128) at org.jbpm.pvm.internal.tx.SpringTransactionInterceptor.execute(SpringTransactionInterceptor.java:79) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:54) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:55) at org.jbpm.pvm.internal.jobexecutor.JobExecutorThread.run(JobExecutorThread.java:63) Here's my timer definition: <custom expr="#{customWaitActivity}" name="Custom Wait" g="411,174,126,52"> <on event="TimeoutEvent"> <!--<timer duedate="30 seconds" />--> <timer duedate="30 seconds" repeat="30 seconds" /> <event-listener class="jbpm.demo.wf.spring.SpringEventListenerDelegate"> <field name="beanName"> <string value="timerExpireHandler" /> </field> </event-listener> </on> </custom> Spring is used to control all the transactions in my project. All the other functions work fine so I think this may be a Spring integration bug of Timer.
