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

Johan Compagner updated WICKET-470:
-----------------------------------

    Attachment: AjaxFormChoiceComponentUpdatingBehavior.java

I already wrote such a thing, don't know if it does take all kinds of radio choices or checkbox choices
because  of this:

                asb.append("function attachChoiceHandlers(markupid, callbackscript) {\n");
		asb.append(" var choiceElement = document.getElementById(markupid);\n");
		asb.append(" for( var x = 0; x < choiceElement.childNodes.length; x++ ) {\n");
		asb.append("   if (choiceElement.childNodes[x] && choiceElement.childNodes[x].tagName) {\n");
		asb.append("     var tag = choiceElement.childNodes[x].tagName.toLowerCase();\n");
		asb.append("     if (tag == 'input') {\n");
		asb.append("       Wicket.Event.add(choiceElement.childNodes[x],'click', callbackscript);");
		asb.append("     }\n");		
		asb.append("   }\n");
		asb.append(" }\n");
		asb.append("}\n");

I am not going deeper then just the child nodes of a radiochoice or group
But for the default CheckboxMultiplyChoice or RadioChoice it should work fine.
I am still thinking about integrating this into AjaxFormComponentUpdatingBehavior so that it checks for the type
and then does different things depending on this.

> 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();
