handling state of the check box

umark

i am working on a series of jsp(struts)pages and at the end, the last jsp page shows the various values given in the earlier pages and provides a button to modify. this button takes me to the first page in the series. if I uncheck a checkbox during modification and reach the confirmation page, it is still showing the check box as selected. i am putting all the values in a session object. i.e., the uncheck action is not effected.

can anybody plz help me in this regard.
