Virtual product - not available to order "only" online product

[Sedzik]

Hi there,

 

i add to my shop virtual product which from definition should be available to buy only in online way.

 

But when in product settings this product is available only online nobody can add it to basket.

 

The availability is only in situation when in product option i pick thath product in available online and in order (from stationary shop).

 

Then you can add product do basket.

 

It is a bug?
