Thanks for your answer. Yes, this works, but here $f is an instance of =20=

Foo, not Bar. When you make it an instance of Bar you get NULL. I =20
think this is not correct, is it?
Given that we have a ReflectionProperty of class Foo at hand, from my =20=

understanding it should look at an instance of Bar as a Foo and return =20=

the value. Am I missing something?
