How to set default value of h:selectOneRadio button

Question

Hi All

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

Answer 1

Did you try to set the addressFlag as an Integer?

private Integer addressFlag = 0;

public Integer getAddressFlag() {
    return addressFlag;
}

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

I did a little test, it works just fine as expected, but I also observed that when you leave out the <h:form> tag, the behaviour of radio buttons is unpredictable and dependent on the webbrowser. The JSF-generated HTML output looks correct, but the webbrowser would in the view only select the button which was actually selected by the user in the previous request on the same page. If the cache is empty, none of the buttons is selected. At least, that was the case in FF.

So, it look like that you're forgotten to put a <h:form> around it.
