checkGroup - 2 out of 5?
Hi,
I want to limit users to check exactly 2 options out of X. How can I do
that? I'd also like it to switch last chosen one to new one, if user has
already picked 2 [so it'd deselect last one and choose another, instead of
not doing anything at all].

To switch the last check with the first checked in case there are two of
them checked already, you could also use an
AjaxFormComponentUpdatingBehavior to do it server-side, though that would
only be disadvantages. I remember some nasty issues with the onchange event
on checkboxes with IE, and the server-side ajax would be just doing dom
attribute manipulations. You'll be much better off doing it with JS, as Igor
stated.

I'd do it with a component validator. That would avoid the Form's onSubmit
being called and getting the model updated with incorrect user data. Or also
with a FormValidator. If I remember correctly, you can call
getConvertedInput to get the Checkgroup's list of selected values.
