Passing parameters between portlets with in the same page

Question

Hello,
I have created a Form and a report. The form allows a user to make some selection values, and then upon submit it passes the selected values to the report to query the database. The results from the query are displayed in a new - seperate - window from the form. Is there anyway to disaply the report results on the same page as the form that called the report? I guess I am trying to have a page with 2 portlets (a form, and a report). I want the user to be able to make a selection from the form portlet and pass that selection to the report portlet within the same page.
Thanks,
McKell

Hi I received this info from an OSS named Mahantesh. I thought it was very helpful information for passing portlet parameters between a form and a report within the same page.
Please check these steps to pass parameter from form to report:
This article is based on demo tables EMP and DEPT.
1. Create a report RPT_DEPT using the query 'Select * from dept where deptno= :deptno'
2. Create a form FRM_EMP based on EMP table.
3. Edit the form FRM_EMP => 'Formatting and Validation Options' section => click on DEPTNO field
=> Give the value for the 'Link' (under 'Display options') as 'javascript:runrep()' where runrep is the name<br>
of javascript function that we are going to create later.
4. In 'Form text' section, in the 'Footer Text' add the code for the runrep function as follows.
<script>
function runrep()
var formObj = document.forms[0];
var deptno;
for (var i=0; i < formObj.length ; i++){
if (formObj.elements.name == 'FORM_EMP.DEFAULT.DEPTNO.01'){
//FORM_EMP is the form name
deptno = formObj.elements[i].value;
break;
var url="/portal/page?_pageid=38,1,38_31678:38_31787&_dad=portal&_schema=<br>
PORTAL&deptno=" + deptno;
//modify the url according to your environment.<br>
window.location=url;
}<br>
</script>
5. Modify the URL in the above code with your page url on which form and report portlets have been placed.
6. Goto Page properties => Parameters tab (Parameters and Events option should have been enabled at Pagegroup level).
7. Create a page parameter and map it with report portlet parameter.
8. Now run the page, enter deptno or query the form to get the deptno and click on the link next to deptno field. You should get report with corresponding deptno on the page.
