Hi,

I'm using the Form Groups and I was using the order stuff for the form... the function was asking for the $order but actually is asking for an array of options.

    /**
     * Add a display group
     *
     * Groups named elements for display purposes.
     *
     * If a referenced element does not yet exist in the form, it is omitted.
     * 
     * @param  array $elements 
     * @param  string $name 
     * @param  int $order 
     * @return Zend_Form
     * @throws Zend_Form_Exception if no valid elements provided
     */
    public function addDisplayGroup(array $elements, $name, $options = null)
