The goal of this lib is to play the onchange methods to get values for the fields not yet filled into the received list of values used to createor update a record. Therefore, the values from the user must be preserved. If we don't process on this way and you play the onchange methods on a sale.order for a new line with 'product_id' and 'product_uom_qty', the product_uom_qty will be reset to 1 when the onchange for product_id will be played and we'll lost the initial value for product_uom_qty
