[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2331) StaleObjectException on Timer execution.

StaleObjectException on Timer execution. ---------------------------------------- Key: JBPM-2331 URL: https://jira.jboss.org/jira/browse/JBPM-2331 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0.CR1 Environment: jBPM 4.0.CR1 in a Spring 2.5 application using the standard transaction model (not spring managed) Reporter: Phil Bingley Assignee: Joram Barrez Fix For: jBPM 4.0 A StaleObjectException is thrown on the flush of the ExecuteJobCmd execution. It appears that Hibernate is trying to update the Job record at flush time despite it having been deleted earlier in the transaction. Adding a repeat to the timer definition means that the timer does not try to delete itself allowing the job to execute without an error.
