Hi,
There have been some remarks in the past about mixing PN-typed composite actors in non-process domains, and that these don't seem to work.
Replies then stated that currently process-type composites can only be used inside process-typed hierarchical models.
But I've tried this (with Ptolemy 4.0.1), and seen the following behaviour:
1- a PN parent model, containing composite actors without own director ("transparent" ?) executes and terminates fine
2- a PN parent model, containing composite actors with an SDF director (and containing SDF-compatible actors) executes and terminates fine
3- a PN parent model, containing composite actors with an PN director does not function
I've attached the sample moml file.
The composite actor contains a simple Ramp, linked to an InteractiveShell, and acts as source for a simple string-length calculation and manipulation.
In case (3-), the InteractiveShell gives me the expected prompt, but the cmd I enter seems not to arrive at the StringLength actor in the parent model...
And the execution remains blocked after that...
Can someone explain what are the semantic differences between cases 1 and 3?
Should case 3 function similarly to case 1, or doesn't this case make sense?
What are the underlying components in the Ptolemy SW architecture that intervene in the communication between PN composites and hierarchies?
Kind regards
Erwin
