Impact Combination Weight Does Not Affect Transport

[gerardor]

Hi, I'm doing some repairs at a store in version 1.6.0.8. The fact is that the products have default 0lbs weight, and the weight is controlled in combinaciones.En paragraph 'impact on weight' will increase the total weight of the combination, and that the combinations are highly variable in weight . I realized that configure transport weight, always makes the minimum weight of 0-10 kg in this case, and never look at the weight of the combinations. How could I fix this? I think modifying some file. Thank you. Excuse my bad English.
