> When a user enters a invalid value, the framework logs a WARN msg with stacktrace. Even
when dev mode is disabled.
> For example:
> - an Action with an int as member
> - a form with a text field for that int
> - user enters a string
> The framework tries to find a setter for that member (which is successful) and tries
to set the value (which fails because the setter has wrong parameter type)
> Then a stracktrace is logged as WARN.
> It is a valid use case that users enter invalid data and no stracktrace should be logged
(at least not when dev mode is disabled).
