title: Camunda - why does generated form not appear?
body: <p>I have created a form for a message start event and a user task. I can see in the generated XML something that looks like:</p>
  
  <pre><code>&lt;bpmn:extensionElements&gt;
    &lt;camunda:formData&gt;
      &lt;camunda:formField id="myField" label="My field" type="string" /&gt;
    &lt;/camunda:formData&gt;
  </code></pre>
  
  <p>etc etc....</p>
  
  <p>So it looks like the XML should be defining a generated form for me.</p>
  
  <p>However, when I go to Camunda and try and create a task from the message start event form instead of seeing the HTML form I am expecting, I get a message saying:</p>
  
  <pre><code>This task contains an external form to complete it.  In order to open the external form click on the "Open external form" link below.
  </code></pre>
  
  <p>When I click on the link for the form, I get a 404 error.  The link it is trying to reach is <code>/camunda/app/tasklist/default/MyMessageFormKey</code>. <code>default</code> is the name of the <code>process-engine</code> xml field in the <code>processes.xml</code> file.  The directory <code>default</code> doesn't exist in the path, so should this value be something else?</p>
  
  <p>Is there something I need to do when creating the Maven pom file that builds the task?</p>
