I have an application:

  TabNavigator
    mycomponent1 - Edit parameters
    mycomponent2 - Display A
    mycomponent3 - Display B
    mycomponent4 - Display C

When I have changed some parameters in mycomponent1 I want to fire an
event in mycomponent1, and then in mycomponent2 to mycomponent4 listen
for that event and then do local processing within that specific
component.

I can fire the event in mycomponent1, and I can successfully listen
for it in the main app. But I am having problems setting up event
listeners in mycomponent2 to mycomponent4.

Can anybody help?

Andrew
