In our effort to build a headless Ptolemy model (Giri posted about it earlier
this week), we find that most of our actors do not become "full citizens" of
the new model. As a result, nothing happens when we execute the model. We
tried to model our code on MoMLSimpleApplication and the entity-creation code
in MoML parser:
// The top-level TypedCompositeActor is named "world"
// mote extends TypedCompositeActor
NamedObj moteClone = (NamedObj) mote.clone(world.workspace());
world.workspace().add(moteClone);
moteClone.setName("MoteActor " + i);
((ComponentEntity)moteClone).setContainer(world);
// This differs on purpose from the "_location" parameter
Parameter position = (Parameter) moteClone.getAttribute("position");
// ...
Actors added this way make it into the manager's contained entity list, but not
into the entity cache. When we call execute(), the method returns almost
immediately, and none of the actors we tried to add using the above method are
initialized ...
Thanks for your guidance,
Andy Z.
