Hi Ravi,
You need to call _top.preinitialize() and _top.initialize() first.
I modified CompositeProcessDirector so that if _inputBranchController is
null, then an InternalErrorException is thrown:
Exception in thread "main" ptolemy.kernel.util.InternalErrorException:
_inputBranchController was null\
? Perhaps initialize() was not called?
in .top.<Unnamed Object>

See ptolemy/moml/MoMLSimpleApplication.java for how to use
ptolemy/actor/Manager.java to run your model:
_manager = new Manager(_toplevel.workspace(),
"MoMLSimpleApplication");
_toplevel.setManager(_manager);
_toplevel.addChangeListener(this);
_manager.addExecutionListener(this);
_activeCount++;
_manager.startRun();
Thread waitThread = new UnloadThread();
// Note that we start the thread here, which could
// be risky when we subclass, since the thread will be
// started before the subclass constructor finishes (FindBugs)
waitThread.start();
waitThread.join();
if (_sawThrowable != null) {
throw _sawThrowable;
}
For information about initialize(), see Chapter 5, Designing Actors,
page 178 of Volume 1 of the Ptolemy Design Docs at

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.

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