ZF-3957: Zend_Form->addDisplayGroup with wrong documentation
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)
