Null values have to be represented with special marker strings, and then changed to null as part of using your converter.
http://www.nabble.com/Re:-Nulls-and-hibernate-objects-p10040992.html SelectItem does not allow null as a value for itemValue. I think this might have been fixed for the JSF 1.2 spec. Again, another way to handle this is to enhance tomahawk selectItem (and selectItems) to automatically try to coerce the type like the old f:selectItem did. Submit patches if that's important to you.

And what about null values? How can I make an empty value? It was posible before but I now, I can't add a f:selectItem with a null or empty valueItem and I can't add a selectItem with null value to the list.
