[kepler-dev] Getting exception when using PNDirector

[Ravi Kumar]

Hi All,

I am trying to create and run a workflow programmatically. I have created one and able to run if I use SDF director. But not able to run this using PNDirector. When I export the workflow in xml using exportMoML() method and open the xml file in kepler, it runs properly.

Following error I am getting when trying to execute workflow programmatically  using PNDirector.

Exception in thread "main" java.lang.NullPointerException
      at ptolemy.actor.process.CompositeProcessDirector._resolveDeadlock(CompositeProcessDirector.java:699)
      at ptolemy.actor.process.ProcessDirector.fire(ProcessDirector.java:259)
      at ptolemy.actor.CompositeActor.fire(CompositeActor.java:459)
      at test.BowtieTest.init(BowtieTest.java:64)
      at test.BowtieTest.main(BowtieTest.java:18)


I am not able to find out root cause for this. Any help on this would be really helpful.

Regards,
Ravi
