Setting an item value before print report in BI Publisher

Question

Hi,
I am having an issue with setting a page item's value once a button (that prints a BI Publisher report) is pressed. The session state for the item is set, however because the page does not re-load no value appears in the item on the page.
I am using a button as a page Item and using a Page Branch with the Branch Point set as On Submit: After Processing(After Computation, Validation, and Processing) with the Page set to 0 and the Request set to PRINT_REPORT=REPORT
Is there any way to set the item value on the page before branching to the report?
Your help is greatly appreciated.

Marsha,
You can do that as follows:
1- create a hidden text item (P20_date_hidden) with default value set to sysdate.
2- for your button >> edit >> Buttom display attributes >> attributes >> type in : onFocus= "set_date();" (( note: am using onFocus because it takes places before onClick ))
3- In your page >> edit >> HTML header >> type in :
<script language="JavaScript" type="text/javascript">
function set_date()
v_date = $x('P20_DATE_HIDDEN').value;
$x('P20_DATE_LETTER_SENT').value = v_date;
</script>
Hope this helps,
Sam
