This is because for you the itemLabel was being rendered as the value right?

"Null" is the itemLabel. You'll notice I didn't provide an itemValue
so I guess I was assuming the itemValue would be null if you didn't
provide one (not exactly sure off hand if that's how it works). But
for example purposes you can assume itemValue="#{null}"
