Performing a Bean Backup Action on p: selectOneRadio
I am using a radio component on which, when I select an element, I want to do a bean backing action (not go to the results page, but do some actions and then refresh the current page via Ajax). The problem is I can't get the background action bean to do the execution
<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 bean backing method ...
public void selectRadioItem(ValueChangeEvent event) {
String[] selectedItems = (String[]) event.getNewValue();
//more...
}
Is there something wrong with the code I'm missing? I used the same structure to select many checkboxes that work ...

Rodrigo, there is a difference between valueChangeListener and simple method call via ajax.
Check out this answer from BalusC about the difference between valueChangeListener
and<f:ajax>
To solve your problem, you can use the property listener
<p:ajax>
.
OneRadio component is used to accept only one value, if you want to select a list of values use SelectOneMenu
Try 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 OneRadio component value is now a property that I named radioValue
String radioValue;
...
public void selectRadioItem() {
String selectedItem = this.radioValue;
//more...
}
