Subject Last object in key path
Date Thu, 19 May 2016 17:51:24 GMT
Hey guys,

I’m trying to do something where right before setting a value, I want to
lookup and call a validation routine.  I was looking for a method where I
could get the target object for a given property, but I can’t seem to find
one that’s exposed.

So for a key path of “key1.key2.key3” when setting a value, I’d like to try
to lookup a method on the object represented by “key2” and call that first,
and then conditionally call the set.  Any ideas?
