We are able to use the duplicate product functionality to duplicate a simple product, and later add assign it to a configurable product. That part works OK. The different product sizes show up in the catalog OK, too. BTW, we are adding T-Shirts with different sizes.
So, the problem is when we try to add the products we tried to duplicate to the shopping cart. When we try to add them we get “The product out of stock” error message. This happens no matter what the qty of the simple product is.
Everything works fine if we manually add additional simple products to the configurable product with different sizes. Also, the original simple product always works fine.
The duplicate product functionality is very useful for us, because it safes a lot of time when creating a lot of products manually.
Is this a known issue? Anyone else seeing this?
P.S. This was harder to explain than I thought… I hope you understand the problem.
