Question

I have a simple use case with p:selectOneButton.

I basically want one option to be checked=true but allow users to change. I tried different combinations of only having value set for one but no change.
Pseudo code below:

<p:selectOneButton id="options" value="#{buttonBean.number}">
<f:selectItem default="true" itemLabel="Option 1" itemValue="1" />
<f:selectItem itemLabel="Option 2" itemValue="2" />
<f:selectItem itemLabel="Option 3" itemValue="3" />
</p:selectOneButton>

I tried javascript to no avail, not that I expected it to work since I’m not updating it on the server side…

document.getElementById('options:0').checked = true;

Cheers

You could try:

<f:selectItem noSelectionOption="true"/>

Or, what I would do, initialize number in buttonBean @PostConstruct method:

@PostConstruct
private void postConstruct() {
    number = 1;
}
