jsf - How to set default value of h:selectOneRadio button

Question

I am unable to set the default value of h:selectOneRadio as i need radio button to be pre selected

<h:selectOneRadio id="myRadio" value="#{Externalbean.addressFlag}" >
<f:selectItem itemValue="1" itemLabel="Yes"/>
<f:selectItem itemValue="0" itemLabel="No"/>
</h:selectOneRadio>

and my backing bean is

private String addressFlag="0";

public String getAddressFlag() {
    return addressFlag;
}


public void setAddressFlag(String addressFlag) {
        this.addressFlag = addressFlag;
    }

but no luck

You need to set the default value in the init method of your backing bean:

@ManagedBean
public class YourBackingBean implements Serializable {

    private String addressFlag;

    @PostConstruct
    public void init() {
        addressFlag = "0";
    }

    public String getAddressFlag() {
        return addressFlag;
    }

    public void setAddressFlag(String addressFlag) {
        this.addressFlag = addressFlag;
    }
}
