Passing value of View Attribute from standard page to custom page

Question

Hi everyone,
I have a custom page which needs to be called from a standard page. Now this custom page is based on some parameters whose value will depend on the dynamic selection by user. So how to get the currently executed value from VO.
For ex: Vendor Id , contact id and site Id all are to be fetched which are present in three different VOs. When user select particular vendor, contact and site these values will change accordind to selection.
Here do I need to extend the controller and application module of the standard page or it can be done by passing parameters in destination URI of submit button.
I tried using parameters in destination URI of submit button as {VO.ViewAttributeName} and printing in custom page but it was printing " {VO.ViewAttributeName}" as it is.
Please help..
Thanks in advance.

Hi Meher,
I tried doing it by destination uri but it was not taking the value.
I tried CO extension with the following code in my extended CO :
public class ExtendedByrCntDirCO extends ByrCntctDirCO
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
/* I WANT TO CREATE TEH SUBMIT BUTTON PROGRAMATICALLY */
OASubmitButtonBean oasb= (OASubmitButtonBean)pageContext.getWebBeanFactory().createWebBean(pageContext,"BUTTON_SUBMIT");
oasb.setID("SubmitBtn");
oasb.setUINodeName("SubmitBtn");
oasb.setEvent("xxSubmitButton");
oasb.setText("Submit");
webBean.addIndexedChild(oasb);
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
String url = "OA.jsp?page=/oracle/apps/aeap/Vendors/webui/VendorContactsPG";
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
OAViewObject VendorsVO = (OAViewObject)am.findViewObject("VendorsVO1"); // To retrive the attribute of a particular VO
Number VendorId = (Number)VendorsVO.getCurrentRow().getAttribute("VendorId"); *// But here its showing null pointer exception*
HashMap params = new HashMap(1);
params.put("VendorId", VendorId);
String strEvent= pageContext.getParameter(EVENT_PARAM) ;
if ( strEvent.equals("xxSubmitButton"))
pageContext.setForwardURL(url,
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
params,
true,
OAWebBeanConstants.ADD_BREAD_CRUMB_NO,
OAWebBeanConstants.IGNORE_MESSAGES);
So how can I retrive the value from VO . Is there any another way . Plz help...
