Hi, I'm trying to send an email to the current process actor using the notify="yes" attribute in jbpm 3.2beta. My code is as follows:
<task-node name="Name band">
| <task name="Name band" swimlane="Record producer" notify="yes">
| <controller>
| <variable name="bandName" access="read,write,required" mapped-name="Band name"></variable>
| </controller>
| </task>
| <transition name="" to="Organize vocal tuition"></transition>
| </task-node>
Trouble is that I get a nullpointerexception in the web console. Turning on logging this is the relevant error:
20:51:56,795 DEBUG [GraphElement] event 'before-signal' on 'TaskNode(All contrac
ts agreed?)' for 'Token(/)'
