When attempting to run the "File to Array converter" actor as part of a workflow which creates a text file from the output of a script, then converts the text file to an array and performs various calculations, when the file which is called in the actor is not in place prior to the running of the workflow an exception will occur even when the PN director is used, which should halt the firing of the actor until the file in question has been created by the script. It has been suggested to me that the problem is that the actor makes the call to FileParameter inside the constructor instead of the fire() method.
