thanks. It is true, editing the employee does not make it a different 
employee. That's exactly why I'd prefer to invalidate the property 
without replacing the employee instance ;-)

I realize that making everything observable would solve this problem - 
while creating a new one: server provides a POJO, and for GUI I'd have 
to copy the data to an "FX-Employee" bean. And that's exactly one of the 
topics in this other property thread on the list (blackmagic (I like 
that), property paths, etc).

Personally I don't want to create those FX observable beans shadowing 
the domain beans to get observability. The data of a single employee 
would go from the database to a Hibernate bean to a domain bean to an FX 
bean and back. That's a lot of copying and boilerplate.

But I also realize that there is no easy way to have both. It seems easy 
enough to make markInvalid protected but even then I'd have to find a 
workaround for 2.2.x.
