Server state saving restores view even request params changed for same page

Question

hi all,
i've a problem with the state saving method of JSF... environment: JSF1.1, WAS6, Spring2.0..
i have two buttons those POP UP an IFRAME inside with a details page..
<input type="button" onclick="openDetailsPage('detailsPage.jsp?id=1');" value="show first record's details" />
<input type="button" onclick="openDetailsPage('detailsPage.jsp?id=2);" value="show second record's details" />
detailspage gets the "id" param and query&show the details of the requested data IF THE REQUEST IS NOT POSTBACK... like below;
public void onPreRender() {
if (!isPostBack()) {
// get id from param, query the record and show its details...
problem is; if i set the state_saving_method as "server"; jsf is creating view only for the first time... after that, no matter what record info i sent, it's restoring the old page...
however, there's no problem if i set state_saving_method=client... my details page view is being created in every request...
what may be the problem? when the server state saving method used, it's not creating just restoring the previously opened page in every click...
thanks in advance,
hasan...
