RE: Static Access to Visit Object?

[Patrick Casey]

For what it's worth, if anyone else has this issue, the following approach
works although it'll break if Howard decides to change how he stores stuff
in the session.

                return null;

                String temp = "Total Render time = " + c;
                Log.info(temp);
                HibHelper.closeSession();
        }
