Unless you have a converter, you're not setting the value to null,
you're setting the value to empty string. There's a variety of ways
to handle it. One way might be to use itemValue="#{someBean.null}"
and implement public Object someBean.getNull() { return null; }
Another way is to use a converter and convert empty string into null
values, or you can use a special placeholder value instead of empty
string.
