[TYPO3-commerce] non-existing articles in drop down

[Barbara Wijbenga]

Hey all,

I have a product: T-shirt, which has 2 attributes: Size and Color. I have 
them in the Selected field.
I did Create all producible articles, but I deleted some, because the size 
XXL only exists for the colors black and white.
I have "plugin.tx_commerce_pi1.allArticles=0" in my Setup, so I get two drop 
down menu's for size and color.

Is there a way someone can't select XXL if the color is not black or white?

Greetz,
Barbara
