[SOLVED] Attribute "rows" no considered in Icefaces ace:list component

Attribute "rows" no considered in Icefaces ace:list component

I use the Icefaces 3 double list component in my JSF application. Everything works fine, but I cant limit the size of items despite the use of the attribute "rows". I want to have 10 elements and make scroll if there are more. But every time I have all the items displayed consistently.
