I have a simple workflow defined which simply starts with a task. Deploying the task is not a problem, however when I attempt to start the workflow I get an ObjectNotFoundException from hibernate. I have followed the execution of code and it appears that there have been no inserts to the JBPM_EXECUTION table before attempting to retrieve a record.

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

<process key="TestTask" name="TestTask">

 <start>
 <transition to="review" />
 </start>

 <task name="review">
 <transition to="wait" />
 </task>

 <state name="wait">
 <transition to="end"/>
 </state>

 <end name="end" />


</process>

Note that I have also tried a similar workflow which started with a state, then went on to a task. This worked fine as the execution was created following the signal to the initial task.
