Getting the processor ID in a control callback

[d.healey]

This isn't working

    inline function myControlCallback(component, value)
    {
        local id = component.get("processorId");
        local processor = Synth.getChildSynth(id);  
    }

In this case the processor is a container, I can Console.print the id variable just fine but I get a was not found message when trying to pull in the childSynth.

Edit: Ooops, this might be a false alarm, I think I have possibly not set the processor id for all the controls... I shall check now
Edit 2: Yes I was being dumb I'll leave this here as guidance to others
