Rich:ComboBox key value usage
===

I am using rich(3.3.3) combo box in my JSF application... I wanted to use rich combo box as key value pair. for example I would like to show value to the user i.e. "America" and on the bean I would like to get 1 against "America".

Could someone please let me know... How I can use it on xhtml page. so that after submit I can get "1" if user select America.
