Show new Dialog page on click of Submit in Standard PO page.

Question

Hi Gurus,
Requirement :
to show a dialog page with 'Ok' and 'cancel' button in the STANDARD Purchase Orders OAF Page on the Click of 'Submit' button i.e. before Approval.
Design:
1) write new CO xxCO to extend the standard OrderCO
2) Put dialog page code on click on submit button before super.processFormRequest on xxCO.
3) handle OK on Dialog page, write the code in xxCO to submit the PO (i.e. same code as in Orders CO on click of submit).
Above approach is not upgrade safe and not very much suggested.
Can you please suggest a better approach.
Thanks and Regards,
Sumana.

Hi,
Can anyone tell me the significane of using pageContext.putParameter. I was trying to implement a solution using this command for the above issue.
===============================================
Intial solution without the use of pageContext.putParameter
===============================================
//Standard Code - Order Co
If pageContext.getParameter("SubmitButton")!=null{
-- calls abc method.(private)
//custom controller - xxOrderCO
If pageContext.getParameter("YesButton")!=null{
-- calls abc method. (copy the private method)
else {
super.processFormRequest
Instead of rewriting the standard code in custom controller on click of yes button of Dialog page.
i'll try to set explicity that submit button is clicked. So that it is always handled in super.processFormRequest.
===============================================
solution with the use of pageContext.putParameter
===============================================
//custom controller - xxOrderCO
If pageContext.getParameter("YesButton")!=null{
pageContext.putParamter("SubmitButton","Clicked")
super.processFormRequest
Please provide your valuable suggestions on this.

Sumana.
