JBPM 3.0.2 and Hibernate 3.1 Error ---------------------------------- Key: JBPM-470 URL: http://jira.jboss.com/jira/browse/JBPM-470 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.0.2 Environment: Windows XP Professional. Java JDK 1.5. MySql 5.0.15 Reporter: Luke Mauldin Assigned To: Tom Baeyens The below code cancels a timer after a task is completed: JbpmSession jbpmSession = JBPMUtil.getJbpmSessionFactory().openJbpmSession(); SchedulerInstance.CancelledTimer cancelledTimer = new SchedulerInstance.CancelledTimer("remind",executionContext.getToken()); SchedulerSession schedulerSession = jbpmSession.getSchedulerSession(); schedulerSession.cancelTimers(cancelledTimer); executionContext.getToken().signal(); jbpmSession.close(); When run with Hibernate 3.0.5, the code runs fine. When run with Hibernate 3.1, there is an exception: java.sql.SQLException: Unknown column 'token' in 'where clause'. The sql query generated has a where clause of "where name_ = ? and token = ?". Token is defined as token_ in the database thus the sql query cannot be executed. The relevant portion of the Timer.hbm.xml is: <property name="name" column="NAME_" /> <many-to-one name="token" column="TOKEN_" foreign-key="FK_TIMER_TOKEN"/> The Timer.hbm.xml looks fine to me. If this is not a JBPM bug/error I will post it to the Hibernate issue tracking system.
