No, this doesn't fix the sparse warning, and is way too complex (and
doesn't really work well either.)
Please do the conversion on the value when you assign it to idProduct
and then you will be fine.
Please run sparse on your patch to ensure you got it right, if you would
have done so here, it would have been pretty obvious.
