[rules-users] ClassCastException when comparing date type with literal

[FrankVhh]

This may sound a bit rude, but... why would you want to do such a thing?

If there is a constraint on the message, then why not put that constraint in
the message structure?

Btw, I think it would work by using eval($date < "...") but see no use for
it either.
