possible issue with Productvs ProductStore flags

[Jacopo Cappellato]

Hi all,

I was playing with the ProductStore.requireInventory=Y/N (default rule 
for the products without the flag set in them) and 
Product.requireInventory=Y/N flags and I think I've found a small issue 
with the user interface.

Once you set the flag in the Product to Y or N, there is no way to bring 
it back to null, and so there is no way to return to the store default 
rule for that product.

What is the bast way to fix this? I think it is important since it could 
 affect other fields as well.
