Select first item of RadioGroup with n Radio Buttons
Hello!
I'm currently working on a RadioGroup which includes 1, 2 or 3
RadioButtons. The decision which Buttons will be shown is done at
runtime. However, I'd like to select the first visible button of this
group as the default selection.
Can anybody give me a hint on how I could solve this problem?
I've tried to use the pageBeginRender or renderComponent methods of
the component embedding the RadioGroup. But that didn't solve my
problem. The selection binding of the RadioGroup was set to my chosen
default value, but the at that moment the RadioButtons have already
been rendered and therefore no Button was selected.
Christian
P.S. JavaScript is a solution - I know - but I'd like to solve it
without it ;-)

Well, not necessary any more... sometimes it's quite helpful to
take a break and have a closer look at what you've done...
Using pageBeginRender is definitely the right way to do it.
Thanks anyway ;-)

The way that I would do this is to bind your property to a persistent page
property and just set that property before you call page.activate
MarriedQuestion mq = new MarriedQuestion();
mq.setAnswer("No);
QuestionPage qp = (QuestionPage) cycle.getPage("QuestionPage");
qp.setMarriedQuestion(mq);
cycle.activate(qp);
in your template:
<span jwcid="married@RadioGroup"
selected="ognl:page.marriedQuestion.answer" displayName="Married?"
validators="validators:required">
<input type="radio" jwcid="@Radio" value="No"/> No
<input type="radio" jwcid="@Radio" value="Yes"/> Yes
<input type="radio" jwcid="@Radio" value="Maybe"/> Maybe
</span>

Yes, I bound the select option to a property and I want to set this
property to a default value that my application logic can determine
before the component is rendered. But my question is: when do I
set this value?In what method do I have to set this value so that the
RadioButtons within the RadioGroup can see the value of the
select property of the RadioGroup?

I think that your radio group is bound to a property, in which case, can
you just set your property and the radio group would automatically reflect
this when it is rendered?
