Error while creating a custom LOV

Question

Hi All,
We have a requirement to open a custom page on the click of an LOV
inside a table(n Number of rows will be there in the table). We need to
populate the base page field after selecting a value from the custom page.
We are using a flow layout with a text box and a torch icon. On the
click of torch icon we are using javascript to open the custom Page.
Everything works fine. When we use the cancel/apply in the custom popup
page, we are using javascript to submit the base page. The popup closes,
but the base page is erroring out saying
"You are trying to access a page that is no longer active.
- The referring page may have come from a previous session. Please
select Home to proceed. "
Can we achive this functionality by any other approach?
We cannot use the standard LOV as the page should have much more
functionality than what the standard LOV offers. The client want the
functionality to be in the same way as LOV works.
We have set the Security property of the custom page to 'SelfSecured'.
The javascript used on the click of the torch icon is given below.
function popupWindow(pageUrl,formName,rowId,retainAM,isModal)
     var Nav4 = ((navigator.appName == "Netscape") &&
(parseInt(navigator.appVersion) >= 4))
     if(rowId != null)
          pageUrl += "&xxbgRowId=" + rowId;
     if(retainAM)
          pageUrl += "&retainAM=Y";
     if(isModal)
          if(navigator.userAgent.indexOf("Firefox")!=-1) // For Mozilla --
added for BUG#2339
               var versionindex = navigator.userAgent.indexOf("Firefox")+8;
               if (parseInt(navigator.userAgent.charAt(versionindex))>=1)
                    openWindow(self, pageUrl,formName ,{width:650, height:450,
resizable:'yes'},'modal','dialog', true);
          else if(Nav4) // For Netscape -- For Mozilla also Nav4 will be true,
but if the browser is mozilla it would be caught in the previous block only
open(pageUrl,'self','width=600,height=400,toolbar=no,menubar=yes,status=1,resizable=yes,scrollbars=yes,modal=yes');
          else // For IE
               openWindow(self, pageUrl, 'modal',{width:650, height:450,
resizable:'yes'}, true);
     else
open(pageUrl,'self','width=600,height=400,toolbar=no,menubar=yes,status=1,resizable=yes,scrollbars=yes');
The javascript used on the click of the cancel button on the custom
popup page is below.
function closeAndSubmitBasePage()
     window.close();
window.opener.submitForm(0,0,{serverValidate:'0',FromPopup:'selectSubmit'});
}

Mukul,
I have tried with the bound value approach also. The popup is coming fine, but when the base page is submitted , it is still erroring out. Also if we close the popup with the browser close (X), and then do some action on the base page, it is erroring out saying
"You cannot complete this task because you accessed this page using the browser's navigation buttons (the browser Back button, for example).".
Now our client has agreed to navigate to another page and come back to the originating page instead of bringing the popup. Since we are close to the release point, I am going ahead with this approach., there is lot to do with the page functionality.
I will try to use the popup again , once the functionality of the page is done and will update you on the same.
Thanks a lot Mukul
