You put the drop down choice in a panel and override populateItem to add
that panel.

This is what is triggering page reload... Do not override it and everything
should work. Use the source Luke

/**
 * Whether this component's onSelectionChanged event handler should be
called using javascript
 * window.location if the selection changes. If true, a roundtrip
will be generated

just this component) and
 * onSelectionChanged being called. This method returns false by default.
If you wish to use
 * Ajax instead, let {@link #wantOnSelectionChangedNotifications()} return
false and add an
 * {@link AjaxFormComponentUpdatingBehavior} to the component using the
onchange event.
 *
 * @return True if this component's onSelectionChanged event handler should
called using
 * javascript if the selection changes
 */
protected boolean wantOnSelectionChangedNotifications()
{
return false;
}

Re: Drop Down Choice default value

[Chris]

Hi,

when using a drop down as follows, always the whole page is reloaded on drop 
down change.

How is it possible to update only a specific component via ajax?

Thanks,
Chris



DropDownChoice tag = new DropDownChoice("tags", new 
PropertyModel(this, "selectedCategory"), displayCategories) {

@Override
protected boolean wantOnSelectionChangedNotifications() {
return true;
}

@Override
protected void onSelectionChanged(String newSelection) {
super.onSelectionChanged(newSelection);
selectedCategory = newSelection;

}


@Override
protected String getNullValidDisplayValue() {
return "All";
}

};


tag.add(new AjaxFormComponentUpdatingBehavior("onchange") {
   private static final long serialVersionUID = 1L;
  @Override
  protected void onUpdate(AjaxRequestTarget target) {
   target.add(...);
   }
});

Re: Drop Down Choice default value

[Marcel Barbosa Pinto]

Another way is to provide a value on your .properties file.

For instance:

nullValid=Please choose
myFieldId.nullValid=Please choose a value for ${label}

Re: Drop Down Choice default value

Hi,

you have to override #getNullValidDisplayValue(), 
#getNullKeyDisplayValue() is for cases where null is *not* valid.

Re: Drop Down Choice

Hi.. If you want only the selected value, you could create a hidden field
to mirror the dropdown's value.

Hi all,

is it possible to have a drop-down box without a list of choices (the list is

Re: Wicket form with AJAX drop down choice and AJAX button not process POST data

Hi again,

Just wanted to update that the issue is resolved. There was a custom script
that sets the content type of AJAX on jQuery.$ to be text/plain and it had
a side effect.

Sorry for the inconvenience.

Re: Wicket form with AJAX drop down choice and AJAX button not process POST data

[Behrooz Nobakht]

Hi again,

I tried the quick start application and tracked down the issue to this.
When a selection is changed (using FireBug/Chrome),

* in the quick start application, I see that  of the request is
Content-Type:
application/x-www-form-urlencoded; charset=UTF-8
* in my application, I see that the content-type of the request is
text/plain

This is why in my application, the request POST data is actually ignored.
I verified that all my HTML files start with


http://wicket.apache.org";>

So, can you please let me know how to fix this?

Thanks,
Behrooz

Re: Wicket form with AJAX drop down choice and AJAX button not process POST data

[Behrooz Nobakht]

Hi,

I've also tested without the prefix input name and it's still the same.

Thanks,
Behrooz

Re: Wicket form with AJAX drop down choice and AJAX button not process POST data

[Martin Grigorov]

Hi,

If you are able to reproduce the problem in a quickstart application then
please attach it to a ticket in Jira.
But I guess the problem is related to the custom prefix you use (#
getInputNamePrefix()).
In FormComponent#getInputAsArray() check what is the inputName and compare
it against the ones shown by Firebug.

Forcing a "No Selection" Option in Drop Down Choice

[Richard W. Adams]

Is there a way to make DropDownChoice  offer "no selection" as the first 
option, even if the input model matches one of the selections? Perhaps a 
property to set, or method to override? Can't find this issue covered in 
the material I've looked at. I'm looking for some technique I can apply 
against the drop down class (or an extension to it) rather than adding 
dummy data to the model.

Has someone already invented this wheel?

Hi!

1. Invisible mode is always possible.

2. Maybe autocompletetextfield will be ok?

3. You can integrate pretty easily a jquery skin.

Drop Down Choice

[Shelli Orton]

Hi,

I've been looking for a Wicket drop down widget where one can choose an
item from the list by typing more than the first character.  For
example, if my list contains the following values:

One
Two
Three
Four
Five

typing "T" would select "Two", but typing "Th" would select "Three".  Is
this possible in Wicket?

Thanks!

Hi
There are mistake in your code: 
programList.setDefaultModelObject(stringObjectModel); 
...may be you  want to call programList.setDefaultModel(stringObjectModel);

Why not set up a property on your page/component for the selected text
and use a PropertyModel?

Martin,
Thanks for the advice. I had a mental fart and left out the setter
function. Once you add the setter...works like a charm. Thanks again.

Re: How to set the value of a Drop Down Choice

[Eric Reagan]

Martin,
I have the following. All I am getting is a null value. Am I setting the
model object wrong?

IModel stringObjectModel = new LoadableDetachableModel<
String>()
{
/**
 *
 */
private static final long serialVersionUID =
2165619560012612599L;
private String text;

@Override
protected String load()
{
return text;
}

};

stringObjectModel.setObject("abc");

DropDownChoice programList = new
DropDownChoice("users",stringObjectModel, users.getAll(), new
IChoiceRenderer()
{
/**
 * Generated
 */
private static final long serialVersionUID = -7278851941695545331L;

@Override
public Object getDisplayValue(Object object)
{
return object.toString();
}

@Override
public String getIdValue(Object object, int index)
{
object.toString()
}
}
);

programList.setDefaultModelObject(stringObjectModel);

Have you tried if setDefaultModelObject() works for you?

How to set the value of a Drop Down Choice

[Eric Reagan]

Hello,
  I was wondering how to set the currently selected value for a
DropDownList? Currently I have a .properties file which sets the value when
I have a null selection, however, I was wondering how do I change the
currently selected value to a different one (e.g. if I  am pulling a
previous selection from a database?)
Thank you,

Well, the effort will nicely blend in with the chores of refactoring
to the changes in generics... :) Or should it be made an abstract
class?

Another possibility would be to just enable suitable hooks in the
rendering phase of xxChoices. I.e., a method "String
getOptionAttributes(T t)" or similar would be called during the render
phase of a DropDownChoice.

It would then be easier for anybody to 'sugarcoat' their DropDown and
it would not break the existing inplementations. There I could just
check if (renderer instanceof MyChoiceRenderer) { ... and sugarcoat my
option ... }

Re: color code options in drop down choice

It would be pretty easy to just add a getDispayStyle method into the
IChoiceRenderer interface and refactor the various classes using it to
support it accordingly. Don't you think?

Re: color code options in drop down choice

[Igor Vaynberg]

so write a component that works the way you want.

as core devs we have to maintain a hard balance between simplicity and
flexibility. the more pluggable/customizable you make something, the
more complicated it becomes.

we do not make core components ultra pluggable because they serve as a
basis and examples for users who want to see how they work and want to
implement something similar. what we do concentrate on a lot is making
writing your own components easy.

if you look at the dropdownchoice class hiearchy you might find a base
class that is a good starting point and will get you 80% of where you
want to go. the other 20% are up to you.

Re: color code options in drop down choice

[Martin Makundi]

Using Select/SelectOption/SelectOptions I loose all the other
encapsulated benfits of DropDownChoice or ListChoice.

Wouldn't it be a good idea to have IChoiceRenderer or a similar
interface with a method getDispayStyle for each option?
