You can use a IChoiceRenderer and pass that to the DropDownChoice along with
your Model and the List. The renderer is used to get the String to be
displayed.

Correct. But if you don't use a renderer they have to be the same
instance to. Otherwise
equals used by list is not recognizing "same object". The renderer takes
that part with
the String getIdValue(T object, int index); method. Here you can
implement the equals
logic.

Please correct me if I am wrong: The model passed in tells the dropdown
which object from the list should be the active one shown. If you don't
apply a renderer then some default is used to render the options and that is
obviously toString() on each object in the list. Ergo: The result object
from evaluating the model should be the same type as the objects in the
list.
