This is not a bug. Please read about JSTL and how it work in JSF. You are not
using it correctly, you cannot use a component variable in a JSP tag, you are
combining apples and oranges.
This should help:

Basically the var in a table is only setup while the table is rendering,
validating, etc, but forEach works during JSP tag execution (when the table
component is being built, not processed). So "app" does not exist at JSP tag
execution.
Rule 1: avoid using JSTL with JSF
Rule 2: really, always avoid using JSTL with JSF
Rule 3: if you have to use JSTL with JSF, make sure you know exactly how JSF
components work and how the JSTL tags are written. I would recommend reading
all the Java sources for JSF and JSTL
