Try dropping the parentheses from ognl:coursePages(). By adding them
you're telling ognl to call a method named precisely coursePages() which
doesn't exist. This is something you'd do only when your method name
didn't follow the usual naming conventions. The expression
ognl:coursePages will call getCoursePages().
