Dropdownchoice without default option "choose one"
I would like to remove the default "choose one" option from the
DropDownChoice component.
Does anyone know how to do this. Thanks.

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.

Just to summarise, you need to do two things: set a 'current selection' and
call setNullValid(false).

I have noticed the problem when I have a propertymodel attached to the
dropdown, and I have two chained dropdowns ... I haven't studied it
much, could fairly well be a stupid user bug.

Yeah, it's easy to miss setting the currently selected value
for when DropDownChoice is rendered for the first time.
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.
Best wishes,
Timo

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.

If you use ListChoice this option is not there. ListChoice does not
extend AbstractSingleSelectChoice .

How to get context path
Posted by "Patel, Sanjay " <sa...@NEMOURS.ORG>.
Hi,
my images in the application are in webapp/image folder. How to get
Context Path in wicket so I can prepend this path to display the image.
I am looking for something like this.
getContextPath() + "image/icon.gif";
Please suggest how to do that.
Thanks,
Sanjay.

Re: Dropdownchoice without default option "choose one"
Posted by Michael O'Cleirigh <mi...@rivulet.ca>.
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.

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.

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));

Mike
