Newbie question: best practices for view update from Composite

Hi everyone,

I apologize for the "stupid" question buy I'm new to GWT.

I have a single page application composed with some nested custom widgets (composites).

I need, from a Composite, to change the main view (i. e. updating the widgets in the entry point class).

Which is the recommended way or the best practice to do that?

Should I use event bus?

Thanks in advance.

D.
