Hello,
I’m using JBPM 4.4 with webpshere.
If I’m having this descriptor:
   <task assignee="HERE" g="507,118,170,52" name="Pause">
                  <transition g="-72,-20" name="to Pause1" to="Pause1"/>
   </task>
*=> No Error*

If I’m using this descriptor with a timer:
   <task assignee="HERE" g="507,118,170,52" name="Pause">
                  <transition g="-72,-20" name="to Pause1" to="Pause1"/>
      <transition g="-17,6" name="timeout" to="Pause2">
                <timer duedate="4 business days"/>
      </transition>
   </task>
*=> I have this error:*

An idea why do I have this error ?
