[jbpm-users] [jBPM Users] - Timer throwing exception intermittently
Hi,
I'm getting the following error at times when my timers are firing.
11:19:51,157 ERROR [ExecuteJobCmd] exception while executing 'timer[46|2009-10-28
11:19:51,040|timeout]'
org.hibernate.ObjectNotFoundException: No row with the given identifier exists:

Sample timer in my process definition:
| <state g="138,450,127,52" name="Validate">
| <on event="timeout">
| <timer name="checkValidity" duedate="3 minutes"
repeat="2 minutes"/>
| <event-listener class="some.class.CheckValidityEvent">
| <field name="idType"><string
value="ID"/></field>
| </event-listener>
| </on>
| <transition g="-72,-22" name="valid"
to="complete"/>
| <transition g="-72,-22" name="invalid"
to="end"/>
| </state>
|
The timers tend to exist though and run just fine on the next timeout.
I'm using jbpm 4.1 on jboss 5.1. Thanks in advance.
