Re: Dropdownchoice without default option "choose one"
I noticed this thread never had a very conclusive answer, so I hope you don't mind if I resurrect it. nitinkc, where are you setting this at? Does it happen to be in the DDC onInit method? I ask, because I have noticed that when it is placed there, it is ignored. Instead I assign the DDC to a var and then do "var.setNullValid(false);", before adding it. This removes the null value for me every time. nitinkc wrote > I tried setNullValid(false). But this does not get rid of the "choose one" > option. Note that the choices are a list of Strings.

Re: Dropdownchoice without default option "choose one"
Thanks gwyn! I was not adding the default value to the ddc and that's why it was showing the "choose one" option. As you said, it's best to do that in the constructor.

Re: Dropdownchoice without default option "choose one"
Just to summarise, you need to do two things: set a 'current selection' and call setNullValid(false). /Gwyn On Wed, Jun 11, 2008 at 6:14 PM, nitinkc <[EMAIL PROTECTED]> wrote: > > I would like to remove the default "choose one" option from the > DropDownChoice component. > Does anyone know how to do this.

Re: Dropdownchoice without default option "choose one"
If you use ListChoice this option is not there. ListChoice does not
extend AbstractSingleSelectChoice .

Re: Dropdownchoice without default option "choose one"
Hi nitinkc,
The "Choose One" option is actually defined in:
public abstract class AbstractSingleSelectChoice extends AbstractChoice
{
/**
*
*/
private static final long serialVersionUID = 1L;
/** String to display when the selected value is null and nullValid
is false. */
private static final String CHOOSE_ONE = "Choose One";
.
.
.
You should look at overriding this method:
protected CharSequence getDefaultChoice(final Object selected) in
AbstractSingleSelectionChoice
It looks to me like if you return EMPTY_STRING then no default choice
will be rendered into the options list.
Mike
I tried setNullValid(false). But this does not get rid of the "choose one"
option. Note that the choices are a list of Strings. If the choices are a
list of other user defined object types and I use a choicerendrer for
display values, the "choose one" option is removed(without
setNullValid(false)). Any ideas?

If the ddc model should always have a value defined then you could set
the model object to be for example the first choice.
e.g. ddc.setModelObject (ddc.getChoices().get(0));

I would like to remove the default "choose one" option from the

Does anyone know how to do this. Thanks.

Hence it's always a good idea to supply it in the constructor. It can get tricky if you want to have the default choice in the UI, but not necessarily update it to the domain object property that the selection is bound to. If this is required, you can get around it by a custom model.

Re: Dropdownchoice without default option "choose one"
I have noticed that with DropDownChoice, if the currently selected value is Null, you get this "choose one" item. And sometimes in a dynamic situation you get it still. Try using the analogous ListChoice element, at least it worked for me. ** Martin 2008/6/11 nitinkc <[EMAIL PROTECTED]>: > > I tried setNullValid(false).

Re: Dropdownchoice without default option "choose one"
Hi nitinkc, Calling setNullValid (false) on the drop down choice should get rid of the default "choose one" text. If the ddc model should always have a value defined then you could set the model object to be for example the first choice. e.g. ddc.setModelObject (ddc.getChoices().get(0)); Regards, Mike I would like to remove the default "choose one" option from the DropDownChoice component.
