Description:
------------
PEAR Package HTML_QuickForm 3.2.4pl1

I have an element named '0' created in this code:
$vehicle[] =& $form->createElement('hidden', 'type', 'checkbox');
$vehicle[] =& $form->createElement('checkbox', 1, 1, 'Yes');
$vehicle[] =& $form->createElement('checkbox', 0, 0, 'No');
$form->addGroup($vehicle, 'is_vehicle', "Is Vehicle", array(" "));

I am trying to retrive the value of the element named '0'. However the code in HTML_QuickForm_group->setValue does not allow for this instance.

the code looks for !empty($elementName) this does not allow for the (int) 0 or (string) 0.

Unfortunatly, I cannot change the name of the element.

a possible fix is below ( around line 166 group.php ):
$index = ( !empty($elementName) || ($elementName === 0 || $elementName === "0") ) ? $elementName : $key;

Reproduce code:
---------------
$vehicle[] =& $form->createElement('hidden', 'type', 'checkbox');
$vehicle[] =& $form->createElement('checkbox', 1, 1, 'Yes');
$vehicle[] =& $form->createElement('checkbox', 0, 0, 'No');
$form->addGroup($vehicle, 'is_vehicle', "Is Vehicle", array(" "));

foreach( $val as $k=>$v){
$element =& $form->getElement($k);
$element->setValue($v);
}

Expected result:
----------------
element is_vehicle[0] to be checked

Actual result:
--------------
element is_vehicle[0] is not checked
