[MERGE] OPW 50627 Issue with act_window

related to this bug: https://bugs.launchpad.net/openobject-addons/+bug/708467

To reproduce the issue:

1 Create a new database with demo and sale module
2. Open Menu Sale/Address Book/Customers
3. Search Agrolait and open it
4. Click on Sales (link)
5. You must see 2 sales
6. Create new sale order
7. The customer field is empty (should have Agrolait)

This happens with all act_windows.
