I have tested your scenario with trunk and stable6 both and it is working fine at my end.
The main issue which you are missing in your code is proper inheriting the tree view. The following patch will add the product code field in the tree view of product.supplierinfo.
After applying the changes it is working so I am again attaching the related changed module would you please
check it and notify us where you faced the problem.
