Pipeline pilot input

Hello,

I just started a few days ago using Pipeline Pilot and I noticed that when you make a subprotocol then you can't have more than one component that takes an input parameter.

I often get my data from javascript functions triggered on event which populate list box for example.

So my question is it is possible to get the components without input parameter (if no what's the way?).

In fact I have already seen the 'custom manipulator' with and without the input pipeline.

Thanks
