Problems With Session State Protection

Question

I have enables SSP on one of my applications and everyting seemed ok until I reached a page with a custom pop up page.
I use this code in my page header
{} used to display code
{<script language="JavaScript1.1" type="text/javascript">
function callMyPopupRank (formItem1,formItem2) {
var formVal1 = document.getElementById(formItem1).value;
var formVal2 = document.getElementById(formItem2).value;
var url;
url = 'f?p=&APP_ID.:115:&APP_SESSION.::::P115_RANK,P115_RANK_ID:' + formVal1;
w = open(url,"winLov","Scrollbars=1,resizable=1,width=400,height=630");
if (w.opener == null)
w.opener = self;
w.focus();
</script>}
Then I call it from post element text of an item
{<img src="#IMAGE_PREFIX#edit-white.gif" border="0" alt="Edit">}
When my pop up page opens I get this error
Attempt to save item P115_RANK in session state during show processing.
Item protection level indicates "Item may be set when accompanied by a "session" checksum.".
No checksum was passed in or the checksum passed in would be suitable for an
item with protection level "(No checksum was provided)".
How do I append the checksum to my url ?
Thanks
Gus

Answer 1

You will need to use the APEX_UTIL.PREPARE_URL function to append the checksum to the URL. I would suggest you use a hidden page item to hold the URL and then reference it in your JS.
I hope that helps
