Hi Dave,
I tried it this way but it's the same.
$this->layout = 'ajax';
$this->autoLayout = false;
$this->autoRender = false;
$response['html'] = $this->render('/form/form_json');
So is there a way to get the result content of a view in a var (in
this case $response['html']) without rendering it (= without getting
the annoying echo) ?
