Re: How to set the initially selected value of a DropDownChoice?

[Kaspar Fischer]

Thanks for the helpful link, Martijn. For the sake of completeness,  
here's
what I have ended up with:

  List<String> PagerSizesList = Arrays.asList("25", "50", "100");
  ValueMap parameters = // ...
  parameters.put("search-page-size", PagerSizesList.get(0));

  form.setModel(new CompoundPropertyModel(parameters));
  form.add(new DropDownChoice("search-page-size", PagerSizesList));

How can I set the default value of a required DropDownChoice that
should not have null values?

  private static final List<String> PagerSizesList =
Arrays.asList("25", "50", "100");

  // in constructor...
  DropDownChoice pagerSizer = new DropDownChoice("search-page-size",
PagerSizesList);
  add(pagerSizer);

I've tried overriding my DropDownChoice's getDefaultChoice(),

      @Override
      protected CharSequence getDefaultChoice(final Object selected)
      {
        return "<option value=\"\">" + PagerSizesList.get(0) + "</
option>";
      }

but this replaces the label of the null string, but does not remove
the null string itself.

Thanks and best wishes,
Kaspar
