"Product is not available in this combination" in product without combination ( ಠ_ಠ)

[hakeryk2]

Hello community,

I have strange error on product page when I have product with no combinations and I want to to url like http://domain.com/product512.html#footer then this information appears and button "Add to cart" dissappears.

This not happens on product with combinations and everything works smoothly.

Does anyone now how to edit product.js to prevent situation like this?

EDIT: Solved. 

In product.js, in checkUrl function I added this condition:

 

function checkUrl()
{
	if (combinations.length == 0)
		return false;

// ... rest of this function

------------------------------------------------------------------------------------------------------
EDIT 2: Not solved
The solution above is breaking displaying of images in jquery :/
----------------------------------------------------------------------------------------------------

EDIT 3: Solved

if (typeof combinations === 'undefined' || !combinations){
        return false;
    }
