You can do this:
SelectItems[] items = new SelectItems[] {
new SelectItem("", "(none)"),
new SelectItem(1, "one"),
...
};

If I recall, one of the constructors does allow you to inconsistently

Unfortunately not, at least in 1.1.1 (the version I'm currently
using); the only constructor that doesn't have the check is the
no-args constructor :-)
And in JSF 1.2, I just saw a change-request go through to allow nulls.
Ah, so this is a spec-enforced limitation?
However, I use a flag value.

That works, provided you're willing to define a converter for every
use of select items... I'd rather avoid having to add a bunch of
converters just to allow this :-( Unfortunately, it sounds like the
only way to do that may be to write a custom component, which seems a
bit crazy...
I'll have a look at whether there's support for this in Tomahawk or
Trinidad first, though.

How do I create an 'empty' SelectItem? I'd like to present a
selectOneChoice which allows the target model value to be set to
'null'.
But I can't create a 'null' SelectItem:
SelectItems[] items = new SelectItems[] {
new SelectItem(null, "(none)"),
new SelectItem(1, "one"),
...
};
The SelectItems constructor has an explicit check for a null value or
label. Short of inventing a 'flag' value for every option list and
using
a custom converter to translate it back to 'null' during apply values,
how do I get an 'empty' item in my SelectItems array?
