Re: [Wicket-user] can't get rid of "Choose One" in DropDownChoice

[Vincent Jenks]

Why have the default message at all?  Why provide something for developers that they should be determining themselves?  The default should be the first item in the list...if you need a default, override the method and provide one.

yes moving the method to the renderer and calling that render method in the choice method is fine by me.
Except what is then the default "Choose one" ?
We can add it ofcourse in our default renderer: ChoiceRenderer
But then you have to specify it or subclass choicerenderer. Else suddenly you don't have that default message anymore.

Got it, thanks.  It's confusing that it doesn't work like I described, even though the method can be overridden.  It'd be convenient to be able to do it how I posed verses doing this:

        //create calendar
        List<String> days = DateTime.getDaysListForward(2, 4);
      

        DropDownChoice arrivalChoices = new DropDownChoice("arrivalDate", days)

        {
            protected String getDefaultChoice(final Object selected)
            {
                return ""; //get rid of "Choose One" default
            }          

        };
      
        arrivalChoices.setChoiceRenderer (new IChoiceRenderer()
        {          

            public String getDisplayValue(Object object)
            {
                return object.toString();
            }
          
            public String getIdValue(Object object, int index)
            {
                return object.toString();
            }                      

        });
      
        form.add(arrivalChoices);

you are putting getDefaultChoice into the renderer, when it actually belongs in the DropDownChoice

When rendered...I still get the "Choose One" option first.  Did I lose too much sleep last night...what did I miss?
