Re: Checkbox event
Maybe a variation of the method proposed in
http://wiki.apache.org/myfaces/SubmitPageOnValueChange is useful to
you. You can have a hidden (with css) button that is clicked
automatically when you select the checkbox...

That was helpful. But, I would like to try some other way to utilize the power
of JSF :).
Is there a action event or valuechange event for checkbox. Any idea?
Thanks.

Hi,
I need to display a list box when a checkbox is clicked. I guess we need

Does anybody have some examples of using onSelect in the backing bean?.
Any help
is appreciated.
onSelect is a *client side* thing only. It is a normal HTML feature that
allows an arbitrary piece of scripting to be run in the browser. Nothing
to do with JSF at all.
You could implement what you want entirely on the client by ensuring
your page includes the listbox, but with its style set to display:none.
You should then be able to specify some script in the checkbox onSelect
attribute which finds that component and sets its style to visible. This
is really not JSF at all but that doesn't mean it's a bad solution.
Alternatively, I expect you could map the checkbox value to some boolean
value on a backing bean, and use the same value to control the
rendered attribute of the listbox.
h:selectBooleanCheckbox value=#{someBean.listBoxEnabled}/
h:selectManyListbox rendered=#{someBean.listBoxEnabled} ... /
The problem here is that you need some mechanism for submitting the
entire form back to the server when the checkbox value is changed so the
page can be regenerated.
Maybe you can use tomahawk's collapsible panel control instead of the
checkbox/listbox combination, and avoid the whole issue?

RE: Checkbox event
If you really want the checkbox to invoke a back-end action, I believe
you'd have to do a short onselect JavaScript call to automatically
click a hidden h:commandLink component that itself is defined to
invoke the action. That's because actions are normally invoked only as
a result of clicking on a link or button.
