You can't save it? What can't you save? What happens?

Also, what are your bindings for the WOPopupButton? Can we see it's 
snippet from the .wod?

Why two editing context variables?

You are assigning them to the same context. 
(session().defaultEditingContext())

It is usually considered dangerous to assign this to a variable, I 
usually subclass my components from a common parent that has 
convenience methods like:

public EOEditingContext ec() {
	return session().defaultEditingContext();
}
