I set it to return selection.get(config) and it still doesn't select anything.
I have this now:
IModel selectionModel = new Model()
{
public void setObject(Component c,
Object o)
{
selection.put(config,
Integer.parseInt((String)o));
}
public Object getObject(Component c)
{
return selection.get(config);
}
};
...which is still producing this:
<select wicket:id="quantity" name="cartView:0:quantity">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
</select>
I don't want to work directly on the cart object since I have a method
in another class that accepts a Map....and I'm reusing that method
throughout the cart. I don't want to write another method or alter
the one I have to get around this issue. It works well as it takes
the map apart, determines if the object already exists, adjusts the
quantity, etc. I want all cart item additions, adjustments, etc. to
flow thorugh this single method.

furthermore, if you wanted you can work on your cart object directly instead
of having to translate to and from the map.
