[jboss-dev-forums] [Design of JBoss jBPM] - how to create variables with Expression in processdefinition

[jamjar]

I want to create a variable -"var1" ;
processdefinition.xml:

  |    <start-state name="start">
  |       <transition name="" to="task1"></transition>
  |    </start-state>
  |    <task-node name="task1">
  |      <event type="node-enter">
  |          <script>
  |            <expression>
  |               #{contextInstance.createVariable("var1","value1")}
  |            </expression>
  |          </script>
  |       </event>
  |       <transition name="" to="end1"></transition>
  |    </task-node>
  |    <end-state name="end1"></end-state>
  | 
but i get errors :

  | Sourced file: inline evaluation of: ``#{contextInstance.createVariable("var1","value1")};'' Token Parsing Error: Lexical error at line 1, column 2.  Encountered: "{" (123), after : "#": <at unknown location>
