When sending the JSON-encoded result, there's a little trick: the javascript wants the `hasChildren` attribute to be a boolean. But the SQL result just contains 0 or 1, so we have to convert it, at least for the "false" case. Instead of operating on the string result, one could modify the PHP array with a `foreach`.

The `exit()` might not be necessary, but if you enabled the logs to Firebug, then Yii will write some JS at the end of your response, and it will break your AJAX.
