Some return values are not supported by the XML-RPC interface

product_pricelist.price_get_multi() returns a dictionary with integer as keys. Unfortunatly this is not supported by xmlrpclib.

>>> try:
...     oerp.execute('product.pricelist', 'price_get_multi', [1], [(700, 1, 0)], {'lang': 'de_DE'})
... except Exception as e:
...     print e.oerp_traceback

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/openerp/service/wsgi_server.py", line 83, in xmlrpc_return
    response = xmlrpclib.dumps((result,), methodresponse=1, allow_none=False, encoding=None)
  File "/usr/lib/python2.7/xmlrpclib.py", line 1085, in dumps
    data = m.dumps(params)
  File "/usr/lib/python2.7/xmlrpclib.py", line 632, in dumps
    dump(v, write)
  File "/usr/lib/python2.7/xmlrpclib.py", line 654, in __dump
    f(self, value, write)
  File "/usr/lib/python2.7/xmlrpclib.py", line 733, in dump_struct
    raise TypeError, "dictionary key must be string"
TypeError: dictionary key must be string

I can provide a patch that converts the keys to strings accordingly. The same is done by the json module.

Should I submit a patch or is there a better way to access the function using oerplib?

One needs to use the new JSON RPC interface. 

# price_get_multi(self, cr, uid, pricelist_ids, products_by_qty_by_partner, context=None)
>>> cnt = oerplib.rpc.ConnectorJSONRPC('SERVER_NAME', port=8069)
>>> cnt.proxy.web.session.authenticate(db='DATABASE_NAME', login='USERNAME', password='PASSWORD')
>>> r = cnt.proxy.web.dataset.call(model='product.pricelist', method='price_get_multi',
...                                args=[[1], [(700, 1, None)], {'uid': 1}])
>>> if 'error' not in r:
...     print r
... else:
...     print r['error']['data']['debug']
{u'jsonrpc': u'2.0', u'id': 154493018, u'result': {u'item_id': 1, u'700': {u'1': 0.06}}}
