      BAPL-1727 introduces MVEL expressions to update a specific field of a process variable. 

      The current BPMN Editor let the user define a free expression like in the following Screenshot:

      Output data assignment

      The BPMN output is:

      <bpmn2:dataOutputAssociation>
  <bpmn2:sourceRef>_24F9FADA-068E-4194-8B94-B523520CFDFF_aOutputX</bpmn2:sourceRef>
  <bpmn2:assignment>
    <bpmn2:from xsi:type="bpmn2:tFormalExpression"><![CDATA[_24F9FADA-068E-4194-8B94-B523520CFDFF_aOutputX]]></bpmn2:from>
    <bpmn2:to xsi:type="bpmn2:tFormalExpression"><![CDATA[#{test.prop}]]></bpmn2:to>
  </bpmn2:assignment>
</bpmn2:dataOutputAssociation>

       According the following comment it's wrong from BPMN spec perspective:

      https://issues.redhat.com/browse/BAPL-1727?focusedCommentId=15562175&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-15562175

      This is the desired outcome:

      <bpmn2:dataOutputAssociation>
  <bpmn2:sourceRef>_24F9FADA-068E-4194-8B94-B523520CFDFF_aOutputX</bpmn2:sourceRef>
  <bpmn2:targetRef>test</bpmn2:targetRef>
  <bpmn2:assignment>
    <bpmn2:from xsi:type="bpmn2:tFormalExpression"><![CDATA[_24F9FADA-068E-4194-8B94-B523520CFDFF_aOutputX]]></bpmn2:from>
    <bpmn2:to xsi:type="bpmn2:tFormalExpression"><![CDATA[#{test.prop}]]></bpmn2:to>
  </bpmn2:assignment>
</bpmn2:dataOutputAssociation>

      From a user perspective a desirable behavior could be:

      1. From drop down select mapping expression
      2. A new drop down list let the user select the variable
      3. A new input box let the user fill in the mapping expression this.prop

      TO BE EVALUATED Does is makes sense to ask the user to pre-pend #{ and post-pend }?
