Wrap your head around the idea that the model controls the view. Even the
"data" portions. You should bind your combo box dataprovider to the model
property storing that data (from server based on combo box 1 selection). Why
you don't need cairngorm for enabling? You can just set you're 2nd combo box's
enabled property to {combobox1.selectedIndex > -1}. An alternative using
cairngorm is if your dataprovider (in the model) is null, disable combo box 2,
if it has data, enable it.
Hope this helps!
