Execute Backing Bean Action on p:selectOneRadio - ajax

Question

I'm using a radio component on which, when selecting an item I want to execute an action on backing bean (not navigate to an outcome page, but to perform some action and then update current page via Ajax). Problem is I can't get the backing bean value change listener action to execute
<h:form id="one-radio">
<p:selectOneRadio layout="grid"
valueChangeListener="#{myBean.selectRadioItem}" >
<p:ajax process="#this" update="#form" />
<f:selectItems value="#{myBean.radioOptions}" var="radio"
itemLabel="#{radio.name}" itemValue="#{radio.id}" >
</f:selectItems>
</p:selectOneRadio>
</h:form>
and the backing bean method...
public void selectRadioItem(ValueChangeEvent event) {
String[] selectedItems = (String[]) event.getNewValue();
//more...
}
is there something wrong in the code which I'm missing? I've used this same structure for select many check box which is working...

Rodrigo, there's a difference between valueChangeListener and a simple method call via ajax.
Check this answer by BalusC about the difference between valueChangeListener and <f:ajax>
To solve your problem, you could use the listener property of <p:ajax>.
OneRadio component is used to receive only one value, if you want to select a list of values, use SelectOneMenu
Try to do the following:
<p:selectOneRadio layout="grid" value="#{myBean.radioValue}">
<p:ajax process="#this" update="#form" listener="#{myBean.selectRadioItem}"/>
<f:selectItems value="#{myBean.radioOptions}" var="radio"
itemLabel="#{radio.name}" itemValue="#{radio.id}" >
</f:selectItems>
</p:selectOneRadio>
In the backbean, you can remove the event parameter, because the value of the OneRadio component now is a property, which I named as radioValue
String radioValue;
...
public void selectRadioItem() {
String selectedItem = this.radioValue;
//more...
}
