[development] Array of fields on an admin settings form

[Randy Fay]

I find no problems with this code...

function form_default_some_form() {
  $default = '';
  $options = array('' => 'none', 'a' => 'a', 'b' => 'b');
  $form['myform']['mytypes'][$key] = array(
   '#type' => 'select',
   '#title' => 'Example select',
   '#options' => $options,
   '#default_value' => $default,
  );
  return $form;
}

It performs as expected on D6.16. I thought that the use of an empty string
for a key was screwy, but it doesn't seem to affect anything. (But remember,
that empty($string) will return TRUE where the string has nothing in it,
thus affecting lots of code you might not want to affect.)

Be careful that you don't have your browser tricking you by autofilling the
form. Ctrl-refresh or Shift-refresh or clear the cache. Try another browser.
