pageContext doesn't have a getSession() method

Are you sure about this? (http://docs.oracle.com/javaee/6/api/jav ... getSession())

[admin]

You are right. The option is still wrong but the explanation is incorrect. It has now been fixed.
"Ideally, the argument to the not function must be a booean. pageContext.session does not return a boolean and so this should not work."

thank you for your feedback,
Paul.
