Problem showing a text when you run out of stock and orders are allowed

[santinuro]

Hello guys,

I have a problem or maybe it´s something that doesn´t work well in Prestashop

When a product has no stock and we want customers can order the product. We can, in the quantities tab, mark the option "allow orders: when there are no stocks". And in "Text shown when pending orders are allowed" write for example; Reception in 15 days. Well, showing this text when there is no stock and allowing orders is really interesting.
 
The problem is that this does not work on products with combinations ... If there is a product with combinations, there is no stock in a specific combination and you allow orders, no text is shown notifying the user.

 Is this a problem of Prestashop? Is there any way to solve it?

 

Thanks
