Thanks for the info Mathias. Despite I don't get the ClassCastException anymore, the right page of my dataTable isn't displayed. I have initted the attribute value of my bean to new Integer(0). Then, by displaying its value through the pages scrolling, I see that it keeps its 0 value (normal as I also saw that the setter of the attribute is never called). I can't imagine that it is the programmer's work to update this attribute value ... no ? And if so, where and how ?

It´s just the integer value of the zero based row index for the first row of the table. The instance should be of java.lang.Integer.
