In Litium accelerator there is a link list shown in the header of page called TopLinkList. This is a link list on a page (linkModels). When fetching these links we get all pages in list, even if they are not published or the user does not have read persmission to the page. We added a check on the link model to be AccessibleByUser and now we only get pages the user has page read permission to. But we still get unpublished pages. How do we exclude unpublished pages?
