Subject: Triggering execution on an asynchronous event

I have a Paraview source module thats connected to an external process by a socket. When that process sees fit, it will send a message to the source module that new data is ready. It will then pass the data over, and the source module will grab it. On the next RequestData, the source module will update its outputs with the new data. Unfortunately, I can't seem to figure out how to trigger the pipeline (maybe I don't have the right terminology here) to cause the pipeline to run and the render window to update.

One complication is that I'm in client/server mode, and right now the client is not connected to the external process, just the source modules that run in the server processes.

Can anybody give me an idea of how this should be done? I'm new to PV (and have the book on order). I could be going at this all wrong, for all I know.

Thanks.
