thanks for the explanation chris. but using what you suggested is not making
Print Something appear even once. so the test statement is never evaluated
to true. ...leading me to suspect that ognl expression is not working.
I am not sure whether the random error that is happening for us is being
caused by using ${}. Now that you mentioned it is a security concern to use
that expression under s: tags I am ready to change it to #...considering I
find the syntax to do it..
