[kepler-users] My own actor

[tog]

Hi

I have designed my own actor which encapsulate some grid execution
service. It's behavior is similar to the webservice actor (ports are
created once a provider is chosen).
I used to chain several instances of my actor without any problem.

I now have a problem when I decided to use a
DataInput/WorkflowInput/Parameter/PortParameter to feed my actor
(previously one of my actor was creating some data which was
propagated)

The PortParameter is set using a FileParameter.

When I run my workflow, it fires my first actor which try to get a
token on its input (as usual) but it seems that there is no token
since I get the following message:
                  ptolemy.actor.NoTokenException: Attempt to get token
from an empty QueueReceiver

What is the correct way to read from a PortParamter ?

Thanks
Guillaume
