I have a node type A (equipment) that references node type B (service ticket). When creating a new service ticket, I have a CCK field from which I choose a user (customer) to whom this service ticket belongs.
Then, I click the reverse link to create a new node A (equipment) which has CCK fields to record the equipment info I need for the service ticket (make, model, serial number, etc.).
What I'd like to do is add a CCK user reference field to the node type Equipment which is automatically populated by the user reference field in node type Service Ticket.
