Hi,
I have CheckGroup<User> group = new CheckGroup<User>("usersGroup", list);
and in repeater I add checkbox: item.add(new Check<User>("checkboxUser",
group));
I have got 20 checkboxes, but I want to allow only 5 checkboxes select. When
will be selected more than 5 checkboxes, it shows error (in feedback).
I want to check this when the checkbox is selected (not after submitting
form).
Could help me, how can I do it?
Thanks.
