I\'m using Bootstrap 3.0RC1 with CakePHP 2.3.6. Trying to take advantage of those beautiful looking classes like has-error and has-w
A slightly less ugly solution is to add your selector for that specific type of error div to your bootstrap's CSS file. That way you're not copying all the style values, you're simply adding your error divs to the existing style definitions.
Another option would be to use javascript to change those classes from 'error' to 'has-error' upon DOMREADY, though your page will look strange until that time. Not really a clean solution.
