On your popup page, instead of a list view, you only need a dataview pointed to Artical.  Then when you create a new Artical (with the association to Cart set), you can open the popup page and pass the new Artical.

If you want to see an example of this, on a page with a Cart dataview, add a datagrid of Articals over the association between Cart and Artical.  Then on the New button, right click and select Generate Page.  Studio Pro will generate an example of this page for you.
