A Check button with only one possible state?
That's odd...

Type 2 fields are check boxes.
See the first comment in this FAQ entry:

I assume that you get the different states for the fields like this:
states = form.getAppearanceStates("myCheckBox");
for (int i = 0; i < states.length; i++)
  System.out.println(states[i]);

In my case, this returns for instance On and Off.
I can then change the state of the checkbox like this:
form.setField("myCheckBox", "On");
or
form.setField("myCheckBox", "Off");
