it already does (and has done so in the past).

PropertyHelper likely is the better place for this, otherwise I agree,
the code has to move out of Target and needs the described semantics.
Actually your toBoolean is not really boolean but follows a ternary
logic of true, false, "some other value including null". Maybe
something like
Boolean toBoolean(Object)
and you'd want
if toBoolean(val) == Booolean.TRUE ||
(toBoolean(val) != Boolean.FALSE && getProperty(val) != null)
so a value of "false" would really mean false.
The code in Target almost does that, with the exception that the
equivalent of toBoolean only works if val is a Boolean instance right
now.

Sounds good.
