> Currently the atmosphere module subscribes components to the EventBus just before they are rendered. Naturally events sent on the EventBus before component rendering are lost. You cannot even save lost events using a BoradcasterCache (https://github.com/Atmosphere/atmosphere/wiki/Understanding-BroadcasterCache).
> It could be advantageous if components are registered on instantiation (just before initialization) and it can be set if the component wants to receive cached events (e.g. @Subscribe(cache=true)) which have been generated between registering and rendering of the component.
