Nadir,

Sure I have a couple of sites setup to use a login page that is part of the Viewers source code. You can find the code for this here http://gis.calhouncounty.org/devsummit2012/devsumit2012.zip It just sets up states on the main index.html page and the initial state is the login stuff and it will not switch states until login is successful. The ASP.net web service included also has the ability based on login to define which main config.xml the user is to receive.

Nadir,

The addSharedData function in the BaseWidget is just a simple function that dispatches an AppEvent. You can do that in your custom mxml yourself.

var data:Object =
     {
          key: key,
          collection: arrayCollection
     };
AppEvent.dispatch(AppEvent.DATA_PUBLISH, data);

Nadir,

You would use widget communication. Widget Communication Explained‌ You will have to edit the Header Controller widget to listen for the data you are sending as well. If you provide more specifics than I can provide more detailed instructions.
