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.
