Mail Action error

[kwokhung]

I got the following error:

Exception: org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.graph.action.MailAction is not a: org.jbpm.graph.def.Action

when I tried to deploy a process definition with

<task-node name='start toothpick line'>


<mail to='[e-mail]' subject='Test01' text='Testing' />

<assignment actor-id='xxx' />


</task-node>
