Hi all, i'm new in this list. We at MBIGroup decided to implement an 
architecture using xmlrpc methods, and an MVC model for organizing 
responsibilies among pieces. So we are developing a frontend in PHP 
which uses a Python backend (xmlrpc server) to get data. Ok, stop 
babbling... The question is: i found that xmlrpc.inc has a 'bug' 
exploited with PHP 4.1.0, about inheritance and global variables. In 
fact, enabling DEBUG messages from the library, i saw the XML received 
from server, and then 'evaling ...' phrase, with the correct code 
(something like new xmlrpcval("test", '') etc etc). But the xmlrpcresp 
returned to high level procedure was empty... and kindof of the value 
returned 'undef'. I inspected the code of the library, and after some 
test, i realized that 'global' calls into class functions/methods did 
not work correctly. Now i included some 'patch' rows, adding a global 
registration of variables (through $GLOBALS superglobal array), and 
everything is working fine. Do you know another way of solving the problem?

Thanks in advance.
Dino from Italy.
