Display of form on user taks failed

[udoderk]

hi all,

currently I have no idea why the form of the user task will be not displayed fo CASE 2. But the form will be displayed for CASE 1. I use the Activiti Explorer 5.10 to deploy the process.

Can anyone identify the reason?
The CASE 1 uses the following XML

It seems, that the "first" human performer block was bad formatted with Eclipse:-/
If i replace it with human performer block from "good" case, the form will be displaxed.
         <humanPerformer id="humanP1">
            <resourceAssignmentExpression
               id="humanP_assignmentExpression">
               <formalExpression
                  id="humanPer_formalExpressions">${initiator}</formalExpression>
            </resourceAssignmentExpression>
         </humanPerformer>
If i format then it with Eclipse, this problem occurs again.

I have reported this case as BUG: if the JUEL value expression ${initiator} is entered in the next line of the XML file, so no GUI mask will be shown.
<humanPerformer id="humanPerformer111"><resourceAssignmentExpression id="humanPerformer111_assignmentExpression"><formalExpression id="humanPerformer111_formalExpressions">
${initiator}</formalExpression>If  if the JUEL value expression ${initiator} used in same line,

<humanPerformer id="humanPerformer111"><resourceAssignmentExpression id="humanPerformer111_assignmentExpression"><formalExpression id="humanPerformer111_formalExpressions">${initiator}</formalExpression>
thus GUI mask will be shown.

That does smell like a bug. Thank you for filing it!

Do you intend to correct this bug in the 5.10 or 5.12?

It might be automatically fixed when Tijs commits his parser refactorings next week.

I'll check it then.
