Flex TabbedViewNavigatorApplication question about sending data

I have a TabbedViewNavigatorApplication with 3 views(ViewNavigator), I can use the navigator.pushView(view,dataobject) from actionscript to navigate to anothe开发者_JS百科r view with a data object of my choice. How do I pass a data object of my choice when the user clicks on the default tab button along the bottom to switch views?

Look into firstData... That will allow you to associate a data object with each tab in the TabbedViewNavigatorApplication.
