switch basemap on mobile application flex

Hello everyone, I have a problem with displaying the base map when I open my application using the switch basemap.
I have developed a mobile application and I used the example of a switch basemaps, but I used a caloutbutton INSIDE tHIS with the list of maps instead the buttons visible on the map. When I launch the application does not load the map but as soon as I click on the calout button to open the list of maps is immediately loaded.
How can I do to display the map as soon as you launch the application without having to click on caloutbutton?
this is my code

Francesco,

Set the selectedIndex on the list component.

<s:List id="bb" requireSelection="true" width="240" color="black" selectedIndex="0">
