Code

if (empty($this->options['exposed'])) {
return;
}
$this
->expose_form($form, $form_state);
// When we click the expose button, we add new gadgets to the form but they
// have no data in $_POST so their defaults get wiped out. This prevents
// these defaults from getting wiped out. This setting will only be TRUE
// during a 2nd pass rerender.
