  Hi all, using latest revisions from trunk in server, client and addons
  (updated yesterday), I found following problem when trying to print a
  report withn a custom parser from a 'osv_memory' wizard:

  [2011-01-13 14:09:56,992][pruebas_alberto] ERROR:web-services:[19]: TypeError: unhashable type: 'list'

  
  It seems that 'exists()' method in 'orm_memory' class (in '/bin/osv/orm.py' file, lines 2092-2096) receives a list of ids, instead a single one. Debugging this from 'report_sxw.py' in 'set_context()' method (lines 371 and so on) there's a call to this 'exists()' method upon a browse record (in my scenario a osv_memory wizard). When trying to resolve this call, I realized that in '__getitem__()' method in 'browse_record' class (orm.py file, lines 180-183) following sentence:

  if isinstance(attr, (types.MethodType, types.LambdaType, types.FunctionType)):
                      return lambda *args, **argv: attr(self._cr, self._uid, [self._id], *args, **argv)
  else:
                      return attr

  always transforms an id in a list of ids, making 'exists()' method fail for 'orm_memory' objects...
  A possible solution to this is making a type-checking in this 'exists()' method, like:

  def exists(self, cr, uid, id, context=None):
          if type(id) not in (int, long):
              id = id[0]
          return id in self.datas

  Anyone got same problem?
  Best regards,
