I am using primefaces-2.2.1.jar, jsf-api-2.0.4-b09.jar, jsf-impl-2.0.4-b09.jar (Mojarra), Facelets. I have got a complex datatable with paging, filtering and sorting.
I have got the following two problems.
1. Sorting is not at all working in my PrimeFaces Datatable. Nothing happens when I click on the column name only the arrow icon moves up and down.
2. After doing filtering if I click on any page number then blank (empty) rows are displayed. For e.g. http://img203.imageshack.us/i/65541713.jpg/

My every element in the list is like this
element 1 - id 231ab4 - String
carsettings - Map
|
|--- car-color: Black
|--- model: Classic A322
|--- manufacturer: BMW
element 2
element 3
