The expression language for "validwhen" tests is very limited. The
sub-expression (remarksRequired) is invalid because there is no
comparison. I assume that you want something like this:

((remarksRequired == 'true') or (*this* != null))

If you want to compare "remarksRequired" to a specific value, you should
do so as indicated above. If you only want to test for it's existence,
then you can use "remarksRequired != null".

Hope that helps,
