Hi !

I have a weird issue there. Here's my code :

class xml_request(osv.osv):
    _name = 'xml.request'
    _columns = {
        'config_id': fields.many2one('synconfig', 'Config id'),
        # [...]
    }
    def name_get(self, cr, uid, ids, context=None):
        res = []
        for rec in self.browse(cr, uid, ids, context=context):
            conf = rec.config_id
            # [...]
        return res

Here's the error:

Traceback (most recent call last):
    File "/home/openerp/server/openerp/netsvc.py", line 297, in dispatch_rpc

EDIT:

Today, monday, I've not changed anything, but the error has changed ! :O Here's the traceback:

EDIT:

Tried upgrading openerp to latest version (still v7), tried with another new database, but I still get this error.
