XML-RPC Server functions delegation

[eluser]coolfactor[/eluser]
I'm having the same problem. I also have my server call inside a library-like class (not a true CodeIgniter library, but loaded and attached to the controller instance in the same way). The XML-RPC server fails to call the method. Here's my config:

Code:

// initialize server
$config['functions']['pingback.ping'] = array('function' => 'MyBlog.process_pingback');
$config['object'] = $this;  // reference to MyBlog object
$this->CI->xmlrpcs->initialize($config);
$this->CI->xmlrpcs->serve();

I'm just closing in on a solution, or at least isolating the problem. I'll report back when I learn more.
