  5. Close the diagram in Eclipse, and then open the workflow file in a text editor.
  6. Find the row that contains flow27 and copy the targetRef, which is the missing task. In this example, it is scripttask3.
    <sequenceFlow id="flow27" sourceRef="add_compiled_policies" targetRef="scripttask3"></sequenceFlow>
  7. Go to the beginning of the file where the lanes are defined and find the ID from targetRef. In this example, scripttask3 is assigned to lane4 with the name Policy Steward.
    <lane id="lane4" name="Policy Steward">
  8. Move the flowNodeRef row to the lane where it should belong. For example, move the scripttask3 row to lane3.
    <lane id="lane3" name="Stakeholder">
  9. Save the workflow definition file.
  10. Open the diagram in Eclipse.

    You can now see the task that was missing in the diagram.
