jbpm 4.3 : Reentering a task that contains a reminder throws exception

desidude123 Jan 17, 2010 2:59 PM

For example : in the process below, initial entry into proc1 works, transition to "checkpoint" works - but when the "checkpoint" decision transitions back to proc1, hibernate "Duplicate" exception is thrown.

Removing the reminder element from proc1 - everything works fine.

<?xml version="1.0" encoding="UTF-8"?>

</start>

</fork>

</task>

</task>

<transition name="morework" to="proc1" />

</decision>

</state>

</process>
