pup bug ?

<a href="#" {popup sticky=true caption="Work Details" trigger="onclick"
		text=$slots[s].work_details}>

if the $text is empty then the error message

Warning: Smarty error: overlib: attribute 'text' or 'inarray' or 
'function' required in 
/home/jp/public_html/includes/Smarty-2.6.2/libs/Smarty.class.php on line 
1101

got round the problem by adding the following line in the popup function

  $text =  (empty($text)) ? '&nbsp;' : $text;

before
if (empty($text) && !isset($inarray) && empty($function)) {
         $smarty->trigger_error("overlib: attribute 'text' or 'inarray' 
or 'function' required");
         return false;
     }


Is it really nesessary to raise an error if text is empty - in my case a 
comments field from a database ?
