[Question] wicket.markup.html.form.Radio

[Alex Objelean]

Why wicket.markup.html.form.Radio component does not extend FormComponent?

I wanted to add a FormComponentUpdatingBehavior to this component and it is not possible because it does not extend the FormComponent, but a WebMarkupContainer.

Thank you!

i've got a similar issue and this topic is already being worked on:

https://issues.apache.org/jira/browse/WICKET-531

targeted for 1.3.0 beta 3

Thank you Jan! Sad thing is that 1.2.x branch will never support this feature.

actually, if you're up to building it from the sources yourself, modifying Radio
to work as you expect is pretty easy.

just remove the 'final' from FromComponent.getValue() and let Radio extend
FormComponent instead of WebMarkupContainer. that should be all.

Try:

    Form f = ...;
    RadioGroup rg2 = new RadioGroup("rg2", ...);
    rg2.setOutputMarkupId(true);
    setupAjaxRadio(f, rg2, new Radio("r3", new Model("abc")));
    setupAjaxRadio(f, rg2, new Radio("r4", new Model("def")));
    ...

  private void setupAjaxRadio(final Form form,
      final RadioGroup radioGroup,
      final Radio radio) {
    radioGroup.add(radio.add(new AjaxEventBehavior("onchange") {
      protected void onEvent(AjaxRequestTarget target) {
        radioGroup.processInput();
        target.addComponent(form);
      }
      protected CharSequence getEventHandler() {
        return getCallbackScript(new AppendingStringBuffer(
            "wicketAjaxPost('").append(getCallbackUrl()).append(
            "', wicketSerialize(document.getElementById('"
                + radio.getMarkupId() + "'))"), null, null);
      }

    }));
  }

Thank you Tong, interesting approach.
  I make it work for me by adding AjaxFormSubmitingBehavior to the Radio component, just to keep in synch the model with the RadioGroup state. But your solution is more elegant.

This works to an extent.  It appears that sometimes (totally random as far as I can tell) I have to click twice to get it to actually invoke the ajax action.

But, once it is invoked, I am trying to enable the drop down and disable the text box via:
[code]
  private void setupAjaxRadio(final Panel panel,
      final RadioGroup radioGroup,
      final Radio radio) {
    radioGroup.add(radio.add(new AjaxEventBehavior("onchange") {

                private static final long serialVersionUID = 1L;
                protected void onEvent(AjaxRequestTarget target) {
                        radioGroup.processInput();
                        if (radioGroup.getConvertedInput().equals(Component.getApplyToRadioGroupChoices().get(Component.AMOUNT_TYPE_GLOBAL)) ) {
                                radioGroup.get("percentGFId").setEnabled(true);
                                radioGroup.get("amount").setEnabled(false);
                        } else {
                                radioGroup.get("percentGFId").setEnabled(false);
                                radioGroup.get("amount").setEnabled(true);
                        }
                        target.addComponent(panel);
                }
[/code]

However, the enabling and disabling of the controls under the radio group are being ignored.
Any idea why?

Thanks.

You mean that in IE you have to click twice?
Use onclick event instead...

Yep, that did it.  Still  a little confused as to why the onchange did not work.

Thanks to everyone for their suggestions.
