Google Code issue: http://code.google.com/p/prettyfaces/issues/detail?id=20

What steps will reproduce the problem?
1. Create a custom function.
Ex:
==== in foo.taglib.xml ====

foo

com.company.Foo

java.lang.String foo(java.lang.String)

==== the function ====
public class Foo{
public static String foo(String foo){
return foo + "hello";
}
}
2. Use it on any page
===== the xhtml file (access through prettyfaces) ====

----
3. Tray to rerender the container where the funcion is through ajax
(richfaces in my case).
Just press the TRY button.

What is the expected output? What do you see instead?
It throws an exception
