Executing window.opener.FunName from Web IC pop-up = Permission Denied

Question

Hello,
I have modified a copy of the BuPaCreate view and controller.  When the user hits save, I open a child window to perform some validation using an external system.  I want to write the corrected values back to the form on the BuPaCreate view and then submit the form.  I created a JavaScript function within BuPaCreate to do this.  I'm running into problems when I try to execute this function from the pop-up window.   It is giving a permission denied error.  I made certain my domain and server names are the same. 
Has anyone else been able to execute a function within a Web IC view in this manner before?  Is there an alternate method for returning the corrected values.
Thank you for any help you may be able to provide.  I promise to reward all usefull answers.
Thank you,
John

<i>If I leave the method setting out completely, it defaults to POST.</i>
-->Yes if you dont use anything, then default value will be "Post". But it will give error when you mention explicitly in case of child window usage.
-->In your code instead of using "element.innerText = val;", you can use
"element.innerHTML = val;
--> You need to use the below code get the value from child to main window:
            <script language="javascript" event="onLoad()">
                   opener.document.htmlb_form_1.fieldID.value = <%= your_value %>;
                   window.self.close();
      </script>
Here is the sample code which handles the child & parent window..Have a look..
Here is the similar example. I used MVC concept:
<b>Note:</b> But instead of Model class i used APplication class. You can change ito MODEL Class where ever applicaable.
Let me know if you have any issue:

      Account Number:
      <htmlb:inputField id          = "Account"
                        showHelp    = "true"
                        value       = "<%= Account %>"
                        onValueHelp = "javascript:window.open('acctpop.do?showppopup=true', '_blank', 'Account Details','width=100,height=300');" />
