Greetings: I have a couple questions regarding modal models, and one general modeling question. 1a. Should I be able to modify extended state parameters from within transition refinements using SetVariable? In the attached simple (but otherwise uninteresting) example, I can successfully SetVariable from within the state refinement and via the transition setAction, but apparently not from within the transition refinement. 1b. When I run the attached simple example the first time after loading it, I get the following error. It works as expected on subsequent runs. What does this error mean? ptolemy.kernel.util.IllegalActionException: Failed to compute schedule:2. Is there any mechanism to reference the current state by name from within a state refinement? I wish to do this for logging purposes. 3. Is there any mechanism to for a model to reference the current top-level director's iteration count? (this is for any model - not just modal models, also for logging purposes) Appreciate the help, Frank PS: Congrats and thanks for the Ptolemy book! I love it! |
