Hi Richard,
Thanks for your help.
I tried it in the way you suggested.
Here is my jsf code
<h:column id="column1">
<f:facet name="header">
<h:outputText styleClass="itemListHeader"
value="SEL"
id="testRadio">
</h:outputText>
</f:facet>
<tri:selectOneRadio id ="radio" required="yes"
styleClass="selectOneRadio"
valueChangeListener= "#{editItemBean.
idHasChanged}"
immediate="true"
partialSubmit="true"
autoSubmit = "true">
</tri:selectOneRadio >
</h:column>
Here is my java code
public void handleRadio1ValueChange(ValueChangeEvent valueChangedEvent)
{
System.out.println("Value Change Event
is"+valueChangedEvent.getSource().toString());
}
I'm getting the following exception.

Can you plese suggest me where I'm going wrong. How can I explore the
syntaxes
corresponding to even captruing methods in backing bean.
I appreciate your help.
Thanks
Krishna.

Subject: Re: Please help me
Krishna,
In order to get help on a mailing list, I suggest that you use a subject
line that is more descriptive of your problem.
With that said, I suggest using the Trinidad selectOneRadio tag that has
the autoSubmit attribute. If you set it to true, then your event
listener will be called when the value changes. I'm not that familiar
with the standard JSF selectOneRadio tag. You might be able to get the
value to submit with an onlClick handler. In my opinion though, the
tr:selectOneRadio with autoSubmit="true" and and a valueChangeListener
is the easier way to go.
