BUG: Pressing the stop-button causes null pointer exception #195

Open GoogleCodeExporter opened 9 years ago

If the data WorkFlowManager is not running then the stop button will cause null 
pointer exception.

Fix so that the button is only available if the WFM is running.
Also put in a check for null for safety.
