Hello, I am looking for help trying to create a reusable composite actor with an optional port. The actor has an input port, a result port, and an optional string port to specify a file name to save the result. I have tried using a PortParameter with no success.
What I have been doing: Create a blank workflow, Drag a SDF director, [set iterations to 1!] Drag a composite actor In composite actor: Add normal port for input, Add PortParameter, for optional string, edit with a unique value Add normal port for output, Drag String Accumulator actor, Connect input to "Input" port and "Optional" Port to String Accumulator Link String Accumulator to output port Close composite actor Drag 2 X String Constant and edit with unique values Link a String Constant to input port Link a String Constant to optional port Drag Display actor, Link output port to Display actor Run, OK, Removing the String Constant linked to the optional port Run, Error "ptolemy.actor.sched.NotSchedulableException: Actors remain that cannot be scheduled!" Opening the composite actor and adding a SDF director, [- see discussion in PortParameter documentation] Run, The default optional value is nowhere to be seen. Re-link a string constant to the optional port Run, The constant value is nowhere to be seen. Cheers, Ian. _______________________________________________ Kepler-users mailing list [email protected] http://lists.nceas.ucsb.edu/kepler/mailman/listinfo/kepler-users
