Cannot use object of type stdClass as array in ****/sites/all/modules/ajax_comments/ajax_comments.module on line 148

Hi, I have php error Cannot use object of type stdClass as array in /sites/all/modules/ajax_comments/ajax_comments.module on line 148
I fixed this with adding:
$field = (array) $field; on line 148
May be you will fix it in your module. Thanks for your work.
