Environment: richfaces 3.1.4 GA, JSF 1.1, Weblogic 8.1, JDK 1.4.2_x.

I am using richfaces suggestion box for autocompletion of some value and its working fine for me as long as I used it over the http.

But if I try to use it over the https , it gives me below js error.

Line 4154, char 5, Object doesn't support this property or method...

It is actually coming on the on prototype.js for the lines

4152: return function(className, parentElement) {
4153: return $(parentElement || document.body).getElementsByClassName(className);
4154: };

This errors come at the time of rendering the suggestionbox after filling some characters in the textbox
