i think you mean to add the projects listview to the categories list view
/item/
your structure is a little dangerous here because you have one ListItem item
obscuring the other. if the outer one were called outerItem and the inner
one
were called innerItem, i think you meant to say outerItem.add(projects) and
innerItem.add(link)
