i have attribute color everything works when color is one word like "blue"
When i have polish name color "blue-green" "-" sign inside in attribute it doesnt switch products?

What should i do to make it work? Add id? to address?

Now i have

ProductName_color in sef address

or maybe i should disable color in sef addres but it looks very nice

When i add id of product to sef it works but in case of two words in color it displays only name and id no color "blue-green"

Hello,
I am sorry, but I do not understand your question.

When child product has color attirbute consisting from two words and dash blue-green the sef urls dont work. They work only for one word color like blue

productcategory/product_blue

but when color is blue-green it should be :

productcategory/product_blue_green

but it doesnt work and shows only

productcategory/product and dont switch child products
