> This is broken as in fact using a null value in a SelectItem causes an <option>Label</option> to be rendered, which when submitted actually has a value="Label" (I *think* this is an http think).
> To fix this requires adding the ability to chain converters to JSF - create a ChainConverter implements Converter, add the original (user defined) converter at the end of the chain, and then put a new, null, converter at the front of the chain.  This might be useful in other circumstances as well.
