hi, did you try adding a temporary item to the errors array in php
just before sending the json back and then removing it in your js code
before checking errors.size(). for example
$json = array('errors' => array_merge(array('REMOVE' => ''), $fp-
>getErrors());
$this->sendJson($json);
then in your js do something like this:
errors.unset('REMOVE');
if(errors.size() > 0) {
// do your stuff
}
this is really just a hack but it might help
