I have also faced the same problem.
if the scope of the bean is request then the data is lost.
But i can get the values of checkbox correctly. This is because i m getting the value of checkbox by calling getValue method of checkbox component.
on the other hand, the rows are empty as the data is fetched from the database.
i think the bean is refreshed if the scope is request.
So, i used getSessionScope.remove() method to remove the bean once i am done with the particular page.
you could also try session scope and then remove the bean.

Subject: Strange problem with dataTable and checkboxes
Hello, I'm facing a strange problem and since I'm not yet expert of JSF I don't understand if this is a bug or the right behaviour.
I'm rendering a form with a text field (call it t1), a checkbox (call it b1) and a dataTable. On every row of the table I have a checkbox, so that I can choose which elements to operate on when I press on the appropriate command button. Think to usual web mail systems where you select messages in the index page and then you press a button to delete them.
If the backing bean of the form has session scope, in the actionListener associated to the command button I'm able to check the state of all the rows, and so to operate on them correctly. Now, the problem is that the array of rows is empty if I set the backing bean to have request scope: is this the correct behaviour? If it is, why I can correctly get the state of t1 and b1, and be unable to get the values of the others components? That's what seems strange to me.
I try to not use session beans because if the user has multiple open windows to the same application, bad things can happens on pages like that one.
An advice would be much appreciated :)
Alex
