Hi, Thanks, for the actionListener tip in the t:commandSortHeader. The only question I have: where do you get the uidata in the actionListener from? Because the only uidata I have stored is from the HTMLDataTable, and this index (by using getFirst()) is again, the index of the whole unsorted collection. Is there any other binding necessary, from where I get another uidata with the info of the first sorted element of the collection? thanks, Klaus

Then you can use UIData.getFirst() to get the index of the first element on the page, but I guess you already know that. Futhermore you can set an actionListener on the t:commandSortHeader: actionListener="#{myBean.actionListener}" with the method in the managed bean: public void actionListener(ActionEvent e) { int first = uidata.getFirst(); List<SimpleCar> list = (List<SimpleCar>) uidata.getValue(); SimpleCar firstItemOnPage = list.get(first); } Now you have your first displayed item on the page. I hope this helps!
