That's a limitation of the XML-RPC library. We can't really do much about it, 
as we don't want to redefine the protocols.
This is the reason, too, that we craft the result of some ORM functions, so 
that they fit this limitation

Title:
  XMLRPC can't handle non-strings as keys

Status in OpenObject Server:
  New

Bug description:
  I recently came across the problem described at http://www.openerp.com/forum/post22813.html - namely that several functions return dictionaries of the format {id1: result1, id2: result2}.

When accessing these functions through XMLRPC (at least using python's xmlrpclib), the use of integer ids as keys causes an error. For example, the following code snippet (using get_product_available from addons/stock/product.py):

stocknum = sock.execute(db, uid, pass, 'product.product', 'get_product_available', p['id'], {'location': stockid})

Results in the traceback:

  File "/usr/lib/python2.6/xmlrpclib.py", line 1199, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib/python2.6/xmlrpclib.py", line 1489, in __request
    verbose=self.__verbose
  File "/usr/lib/python2.6/xmlrpclib.py", line 1253, in request
    return self._parse_response(h.getfile(), sock)
  File "/usr/lib/python2.6/xmlrpclib.py", line 1392, in _parse_response
    return u.close()
  File "/usr/lib/python2.6/xmlrpclib.py", line 838, in close
    raise Fault(**self._stack[0])
xmlrpclib.Fault: <Fault 1: "<type 'exceptions.TypeError'>:dictionary key must be string">

I'm not very experienced with XMLRPC, so apologies if this is a problem specific to python's xmlrpclib, or my use of it.

But if not, then perhaps a solution similar to the last patch proposed on the above forum post - ensuring dict keys are run through str() - would be wise.

This is with OpenERP 5 rev. 2159.
