list view can not process domain with some fields in incoming shipment

[Nicolas Vanhoren (OpenERP)]

To reproduce the bug :
- create new incoming shipment
- add product in o2m field.
- now click the process now button

By looking in the console, you'll see an exception:
Uncaught Error: Domain references unknown field : update_cost

By looking at the xml view, it seems correct (the update_cost field correctly appears in the view)
