I suppose the error also says that the value is a method. So that's
the problem. In FreeMarker methods are first-class values, and you
haven't *called* the method (like `session.isSignedIn()`) just got the
method itself. Anyway, since this looks like a JavaBean property, you
could just write `session.signedIn` (no "is" and lowercase "s").
