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 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

  private static final List 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 "" + PagerSizesList.get(0) + "";
  }

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

Thanks and best wishes,

How to set the initially selected value of a DropDownChoice?

[Kaspar Fischer]

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

  private static final List 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 "" + 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
