Hi All,
I have a problem with the PN director on kepler 2.2. I have a simple workflow: string constant ->
file reader -> custom actor.
The string constant fires only once, but my acotr is triggered twice, and the second times it fails
because there is no token on the input port. I defined the token consumption rate for the input
port, I have overridden prefire to return true only if a token is present on the input port, but the
actor is still fired twice.
This is a snippet from my fire method:
System.out.println(myPort.hasToken(0));
String xml = ((StringToken) myPort.get(0)).stringValue();
This is the command line output, I caught the exception and printed the stack
trace
[run] true

The very same code works flawlessly with the DDF director: any ideas?
Thanks and cheers,
