Mike may have been referring to the usage of "this" when he was talking about the constructor. I create drop downs in constructors with no issue, I have not however used a "this" with a property model.
Wild guess: possibly java is in the process of constructing the object, but DropDownChoice cannot access the "this" yet? On occasion I am using drop downs without choice renderer and setting the initial value OK.
