Hi,
I don't know spring binding, but I think you should try and make a
difference between the pagination (the submitting of the form when
paginating and sorting) and the submiting using the other buttons (search,
cancel) - maybe using a "DispatchAction".
One method for search and another one when paginating (making the same
seach, with the initial parameters).
The form has to be submitted when pagination occurs so it can retrieve the
checked checkboxes.
Cheers,
Narcis
