    Problem with 2

    Christoph M. Newbie

      Hi,
      i tried to include two Forms with a decision over transations. the first works fine, but when the second one is reached and someone claims the task> and tries to view it an unexpected exception is raised. i also tried to rename "outcome" to "outcome2" in task1.ftl but that didnt help..

      Process:

      <?xml version="1.0" encoding="UTF-8"?>
      
      <process name="mailprocess" xmlns="http://jbpm.org/4.0/jpdl">
       <start g="220,16,48,48" name="start">
       <transition to="verify_request"/>
       </start>
       <task candidate-users="peter,mary" form="email/verify_request.ftl" g="181,96,126,52" name="verify_request">
       <transition g="-44,-17" name="reject" to="task1"/>
       <transition name="accept" to="vacation_accepted" g="-2,-42"/>
       </task>
       <task candidate-users="peter,mary" form="email/task1.ftl" g="155,187,92,52" name="task1">
       <transition name="ja" to="vacation_rejected" g="-40,-13"/>
       <transition name="nein" to="end1" g="-42,-18"/>
       </task>
       <end g="125,307,48,48" name="vacation_rejected"/>
       <end g="343,252,48,48" name="vacation_accepted"/>
       <end name="end1" g="240,303,48,48"/>
      </process>


      form task1.ftl and verify_request.ftl are identical:
      <html>
      <body>
      <form action="${form.action}" method="POST" enctype="multipart/form-data">
      
      <#list outcome.values as transition>
       <input type="submit" name="outcome" value="${transition}">
      </#list>
      
      </form>
      </body>
      </html>

      Exception:
      Expression outcome is undefined on line 7, column 8 in email/task1.ftl.
      The problematic instruction:
      ----------
      ==> list outcome.values as transition [on line 7, column 1 in email/task1.ftl]
      ----------
      
      Java backtrace for programmers:
      ----------
