Custom field

I’ve add new Custom field (Select multiple values), link it with Queue
and try to add new ticket.
When i select one of customfield values and try to save ticket i get error:

Can’t locate object method “Id” via package “No object mapping for
field” (perhaps you forgot to load “No object mapping for field”?) at
/usr/lib/rt/RT/Record.pm line 1464.

1460: my $method = “${class}Obj”;
1461: $self = $self->$method;
1462: }
1463:
1464: return $self->Id;
1465: }
1466:
1467: sub LookupTypes { ref($[0]) }
1468:

Where is my mistake?

P.S. RT 3.3.14.
