Yes, I am using xmlrpc in my twisted server.
the server sends queries to a postgresql database.  and there are
situations where data from a numeric datatype is selected and returned
to the calling xmlrpc function.
such as xmlrpc_getVender(vendercode) ...

When a field with datatype numeric is involved my xmlrpc server
application says "can't serialise object ".

would this information be sufficient?

happy ahcking.
