> * Mojarra 2.0.3-b05
> * JBoss AS 6.0.0.Final

>
> See also [Steps to Reproduce] to reproduce it in Metamer.
> I have model which contains null values in one column and when I want to sort
> by such column, I want to let RichFaces consider it and sort it on the end of
> the.
> The java.lang.Comparable itself [1] states that the NullPointerException
> should be thrown when comparing object to null value.
> However for user convenience, it will be better to handle null values in
> consistent way to avoid necessity for defining custom comparator.
