> ChildPropertyTreeModel uses PropertyResolver to look at children.  All good, but if you're outside of the JSF lifecycle, the following line is going to throw a null pointer exception:
>     FacesContext context = FacesContext.getCurrentInstance();
>     return 
>       context.getApplication().getPropertyResolver().getValue(parentData, prop);
> SortableModel has similar code.
> We've just had an internal user attempt to use ChildPropertyTreeModel from a filter.  A little strange, but there's no obvious reason why these classes should only be useable with a FacesContext active (they don't take FacesContext anywhere in the API), and the Application can be retrieved from the ApplicationFactory (albeit more slowly).
