I think you should be able to bind (in the Inspector, when the dropdown 
is selected) the selectedIndex to

Bind to: Parameters (or whatever you call that object controller)
Controller key: selection
Model key path: whateverYouWantToCallIt

This assumes you're using a NSPopUpButton (the dropdown with up-down 
arrows). Things might be different for other kinds of dropdowns.

If you set things up this way, you should be able to give a value for 
the key whateverYouWantToCallIt in the in-parameters to determine what 
item is selected, and the out-parameters will have such a key as well.
