title: Why can't my bpmn xml file be displayed correctly in Eclipse BPMN2 Modeler?
body: <p>I programmatically generated an XML format .bpmn file with no BPMN Diagram elements. I want to use Eclipse BPMN2 Modeler to generate the diagram elements automatically for me. But when I open the file using the Eclipse Bpmn2 Diagram Editor, it only shows me empty pools with nothing in it. I cannot see any detail of my processes. </p>
  
  <p>Could anyone tell me why it is so and how to fix the problem to make it display all the information of my processes?</p>
  
  <p>Due to character number limit, I cannot paste my bpmn file here </p>
  
  <p>Below is the link for you to download my original bpmn xml file and the wrongly generated picture:</p>
