Can you just look what goes wrong just set a breakpoint in ListMultipleChoice.updateModel()
and see why the Collection selectedValues = (Collection)getModelObject(); is not filled correctly.

Description:
I'm using a ListMultipleChoice component to populate a List model object.
When the user selects multiple items in the list, I want the list model
object to be populated with those items.
Problem:
The ListMultipleChoice renders correctly with all the proper 'choices' and
corresponding 'id's from the choice List I provide it. The problem occurs
when I try to submit the form with multiple items selected. After each
submit, the model is only updated with one of the selected items - the last
item in the selection chain. For example, if I submit a form with "A" "B"
and "C" selected (top to bottom). The model List only contains "C".
Desired Result:
I would like the model List to contain references to ALL of the selected
objects in the ListMultipleChoice. Any suggestions on what I'm doing wrong?
Here is the code (1.2-20060122):
ChoiceRenderer renderer = new ChoiceRenderer("name","id");
// ListMultipleChoice(id, model, choice list)
unitAmenities = new ListMultipleChoice("unitAmenities",
new PropertyModel(unit, "unitAmenities"), Arrays
.asList(AmenityType.values()));
unitAmenities.setChoiceRenderer(renderer);
Now 'unitAmenities' is a List<AmenityType> and AmenityType is a 5.0
enumeration containing a 'name' and 'id' String fields. I have, however,
tried replacing the enumeration with a concrete class and a static method to
supply list values to no avail. 'unit' is a model object containing the
'unitAmenities' list.
Here is the simple HTML I'm using to bind this component to 'unitAmenities':
<select multiple="multiple" wicket:id="unitAmenities"
id="unitAmenities"></select>
Thanks in advance.
