debugger cannot access the parent page variable in the included page

Question

I have parent page named userCreated and I include another page in it named confirmationUser using

 <%@include file="confirmationUser.jsp" %>

in the parent page (userCreated) I have the variable registerUser and I am trying to see its value in intellij but I am getting the error when I am using evaluate expression Local variable '' not found in class closure

I am using latest version of intellij

I can see any local variable that I defined in the confirmationUser , what should I do to see registerUser in confirmationUser

when I run the page there is no problem and it is working but I need to debug because sometims I am getting null pointer exception and I want to directly know what is the problem.

Parent Page

  RegisterUser registerUser = null;

Child Page

    <% 
String x = "blabla";

  Boolean developer = registerUser.getPackage()!=null && registerUser.getPackage().getName().equals("Developer");%>

here I cannot see the registerUser variable However I can see x variable in the debugger

Most likely you need to:

1. Configure web facet for your project if you haven't done it;

2. Configure the directory containing your JSP pages as 'Web Resource Directory'.

I suspect (2) is not done and thus IntelliJ has trouble to resolve relative path of the included page.
