Proposal for improving nested controller interaction in JavaFX 2.2

> submitButton.onMouseClicked(clickHandler);

> XPath could be used to traverse and query the graph. The graph can be

I'll leave Rich to expand on this tomorrow (if he feels compelled), but 
given it appears you're closer to my time zone (NZ) than his (US) (or 
you just work late), I thought I'd quickly respond to point you to the 
Node.lookup(String selector) and Node.lookupAll(String selector) methods 
here:

http://docs.oracle.com/javafx/2.0/api/javafx/scene/Node.html#lookup%28java.lang.String%29

You can also find similar methods in Scene:
