Ok so your model contains a city object. You can delete the
get/setCity methods on the model wicket code will not use them.
The get/setObject methods are used instead. You could even use the
default Model if your custom model does not do anything else.
And then do: new CityDropDownChoice("city" , model,
Arrays.asList(Cities.values()));
There is no need for a propertymodel there, since you are interested
in replacing the entire object.

Just forget that, it needlessly makes things complex in your situation.
