Second part of the issue #246249 is about connections between variables included into single JSP file. That's feature we've never supported before. Original text of the issue from reporter is:

fileA.jspf:
<%
String myString = "Hello there";
%>

fileB.jspf:
<%
out.print(myString);
%>

main.jsp:
<%@ include file="WEB-INF/jspf/fileA.jspf" %>
<%@ include file="WEB-INF/jspf/fileB.jspf" %>
<%
out.print(myString);
%>

> Netbeans recognises the myString variable in the main.jsp page, but gives
> the following warning in the fileB.jspf, by highlighting the myString
> variable in red:
> 
> cannot find symbol
>  symbol: variable myString
>  location: class SimplifiedJSPServlet
