Updating combination (end-price influence)

[zielu84]

Hello, bellow I've described my problem, did You encountered the same issue? How You dealed with it without modyfing PS core files?

PS version 1.7.2.3

I have ccouple products with price.

For products I've created attributes. Some of tchem are influencing product end-price.

Based on those attributes I've generetd combinations for my products.

 

If I'm modyfing multiple combination via bulk update on combinations list page and I'm adding product end-price modyfication (for example 0.7 USD) everything saves correctly.

 

If I'm modyfing single combination and I'm adding end-price modification, this particular combination is saved also correctly.

The problem is in that case my other combinations are "nulled", their end-price modification is set to 0 USD after saving my previously mentioned single combination.

 

Anybody can help? I'll owe You a bear or whiskey if we meet
