[Typo3-shop] listing all products using pageAsCategory=1

[Rick - Futuros]

I am using the tt_products extensions with pageAscategory=1.

I have a tree like:
Catalogue (id=6)
  - category 1
	- subcat 1
	- subcat 2
  - category 2
	- subcat 1
  ...etc
  - newproducts
  - brands (id=15)

On the new products page i want to display all products which are 
highlighted.

I use the following TS setup:

lib.highlightproducts<lib.products
lib.highlightproducts {
    defaultCode=LISTHIGHLIGHTS
    recursive = 5
    pid_list= 6,15 #only the id's for catelogue and brands
    PIDstoreRoot=6
}

When i open the newproducts page i get the message "The search was empty"

When i put some of the highlighted products into page newproducts the do 
show up.

So the problem seems to be that the extension only looks within the 
page. Although i've set the pid_list, recursive and PIDstoreRoot.

I even set the different page id's of subpages containing highlighted 
products manually in the pid_list. But this doesn't work either.

Anybody got a clue on what could be the problem/solution
