It returns exactly what you have in your list... that's a String "choice1",
"choice2", etc.
The integer values in the options are used by wicket internally.
If you want to apply integer identifers to your labels you should use a
custom object instead of Strings to feed your DropDownChoice, e.g. let this
custom class have a getValue() and get getLabel() method and use new
ChoiceRenderer("value","label") as 4th argument to DropDownChoice.
This way, you also have 100% control, which value is applied to which label.
