DropDownChoice.setNullValid
public List<String> choices = Arrays.asList(null,"RENDER","ENABLE");
DropDownChoice<String> defaultPerm = new DropDownChoice<>( "perm",
permModel, choices );
defaultPerm.setNullValid( true );
When this renders, I see a select box with 4 options - 2 blanks, and the
two text options.
I expected to only see three - a blank (null) and the two text options.
Is this expected behavior? (Wicket 6.2)

Are you confusing nullValid w/ nullAllowed?

As a followup - if you dont pass the null in the choices list, then it
works as expected.
