ValueChangeListener called twice

[Knudsen, Joe]

Can a valueChangeListener be called twice?  I am using both a binding=
and a value=  on a h:selectOneMenu, and the valueChangeListener gets
called twice.  Wonder if that is an issue with MyFaces I am using
version 1.2.5.  I think I can refactor out the binding statement or I
could add logic to look for the multiple calling.  Any ideas?
