[jira] Commented: (WICKET-470) AjaxFormComponentUpdatingBehavior won't work for RadioChoices

["Matej Knopp (JIRA)" <ji...@apache.org>]

Matej Knopp commented on WICKET-470:
------------------------------------

I think this approach is wrong. Sorry :)

What we should do have method Wicket.Form.serializeElementOrChildren, which would act like this:
if the give element is a form element, return Wicket.Form.serializeElement(element);
otherwise traverse children recursively and serialize them.

This should work for both RadioChoice and CheckboxMultiplyChoice without the invasive javascript you suggested. Unless I'm wrong of course :)

> Below is the generated html and js for a simple RadioChoice("sex", Arrays.asList("M", "F")) with an attached behavior. Notice how wicketSerialize will take the else branch for span elements, so it will always return "". Maybe the behavior should be patched, maybe the js, maybe there is a need for another behavior, I don't know.
> <span wicket:id="sex" id="sex5" onblur="var
> wcall=wicketAjaxPost('test?wicket:interface=:2:testForm:sex::IBehaviorListener:0',
> wicketSerialize(document.getElementById('sex5')), function() { },
> function() { });">
> <input name="sex" type="radio" value="0" id="sex_0"/><label
> for="sex_0">M</label><br />
> <input name="sex" type="radio" value="1" id="sex_1"/><label
> for="sex_1">F</label><br />
> </span>
> wicketSerialize = Wicket.Form.serializeElement;
> Wicket.Form.serializeElement = function(e) {
> var tag = e.tagName.toLowerCase();
> if (tag == "select") {
> return Wicket.Form.serializeSelect(e);
> } else if (tag == "input" || tag == "textarea") {
> return Wicket.Form.serializeInput(e);
> } else {
> return "";
