HTML_AJAX, QuickForm_Livesearch and magic methods

Hi all. I'm extensively testing and using HTML_QuickForm_Livesearch. The integration with HTML_AJAX works good. But in the normal use there is a limit. I dont know if its a my fault... I'm trying to set a large number of livesearch elements in a form. It work great. Every element has an id which is used as target. Every id call a method of a class 'livesearch.class.php' (as you can see on the example in HTML_AJAX or QF_Ls release) The problem is: When I have a large number of elements, i must set for each element an unique id. for each id (target) there is a method on the php livesearch class. So if i have 100 element and every element do the same search search(methods) i must write down 100 equal methods. so, I'm working with PHP5...well.....can I use magic methods? __call __get? I tryed it but seem that the AJAX class ignore this magics methods. Some tips? Thank you very much Regards Giuseppe Dessì
