How to select one Radio button by default.

[vinutha]

This is the code for Radio buttons,
When i run my application, "Button1" should be selected automatically.

<h:selectOneRadio required="true" >
<f:selectItem itemValue="Button1" itemLabel="Button1"/>
<f:selectItem itemValue="Button2" itemLabel="Button2" /> </h:selectOneRadio>

so, how to select one Radio button defaultly.

Thanks,
Vinutha.

You have to use itemValue like:

itemValue="true"

for the button that should be selected by default. The other one should be false then.

Hi Manuel,

I made change like this by adding true to itemValue,
<h:selectOneRadio required="true" >
<f:selectItem itemValue="true" itemLabel="Button1"/>
<f:selectItem itemValue="false" itemLabel="Button2" />
</h:selectOneRadio>

but, its not changing.

Thanks,
Vinutha

In your example code I miss the value of the backingbean within your
<h:selectOneRadio /> Tag.

Normally the option is chosen which is the value of your backing bean.
You can give this value your wanted default value.

I hope this helps.

Hi Vinutha, you forget the value attribute for the selectOneRadio like this:
<h:selectOneRadio required="true" value="#{MyBean.valueAttr}" >
<f:selectItem itemValue="true" itemLabel="Button1"/>
<f:selectItem itemValue="false" itemLabel="Button2" />
</h:selectOneRadio>

so if you put true or false to the valueAttr in your Bean the radio will appear selected.

Hope this helps
