dual component

Hi,

I want to create a component that could be used as a popup or as a full screen.

When the component is called as a popup, it cannot contain an interface output plug (otherwise it throws an exception). The communication is executed using a pair fireevent-handlerevent.

However, when the component is called by other component, and shown as full screen, how can I return to the caller component if the component hasn’t any output plug?

Thanks,

Ricard.
