Description:
------------
Often, a validated form will still have to be returned
to the user because of a problem that occurs during
processing. For example, if you are storing input in a
database and the user's input violates a database
constraint (e.g. UNIQUE indices) you should be able to
find the form invalid and return it to the user.
I've included the code for the method that I add in the
classes I extend from HTML_QuickForm to achieve this
functionality.
Apologies in advance if this is already requested.

Reproduce code:
---------------
/**
* Find an element in a form invalid.
*
* @param mixed $element Name of element or reference
* to element
* @param string $message Message to render to user
* @throws {@see HTML_QuickForm::getElement()}
*/
function findInvalid ($element,$message) {
if ( !is_object($element) )
$element =& $this->getElement($element);
if ( PEAR::isError($element) )
return $element;
$this->_errors[$element->getName()] = $message;
}

Expected result:
----------------
Irrelevant

Actual result:
--------------
Irrelevant

Small mistake in reproduce code:
function findInvalid ($element,$message) {
SHOULD BE:
function findInvalid (&$element,$message) {
To avoid copying object when only a reference is needed.
