Problem using dataScoller in Combination with dataModel

ich habe eine Liste, die 30 Objekten enthällt. ich darstelle sie mit 
hilfe von <t:dataTable> und lässe 10 Objekte pro Seite anzeigen und mit 
hilfe von <t:datascroller> kann ich durch die Seiten navigieren. das 
läuft reibungslos. meine List ist vom Typ Arraylist.

I've got a List with 30 Objects that is displayed with <t:dataTable> and 
use <t:datascroller> to display just 10 and navigate through the sites. 
Everything works fine while the List is of type Arraylist.
If i use dataModel instead of Arraylist just the first Page is displayed 
correctly, next pages are just blank. although datascroller says that 
there are more than 10 Objects.
Can anyone help ?
