PropertyModel is aware of the IModel you are passing and unwraps it.
So depending on what is inside your model you have different options:
-the model contains an object x which has a city property:
make sure x has a getter and setter for city this will be used by the
propertymodel
-the model contains a city object:
do not use a propertymodel at all or use "" as the expression.
