Static field works, dynamically modified element gets lost

I’m new to Drupal forms – trying to figure out a maddening problem.

I have a content type of ‘doc-upload’ with various fields including ‘publisher_code’.

When I define the ‘publisher_code’ field type to ‘text’, and go through my upload process, yada yada yada, the value appears in my $node structure later as expected.

When I change ‘publisher_code’ to “field type: List (text), widget: Select list”, and I try to dynamically populate that element with:

function mymodule_form_doc_upload_node_form_alter(&$form, &$form_state) {

  $publishers = array( 'pub1' => 'Publisher 1', 'pub2' => 'Publisher 2' );

  $form['field_publisher_code'] = array(
    '#title' => t('Select a publisher'),
    '#type' => 'select',
    '#options' => $publishers,
    '#multiple' => FALSE,
    '#empty_value' => '',
    '#empty_option' => '- None -',
    '#required' => TRUE
  );
}

The form displays properly, but when the form is submitted, the ‘field_publisher_code’ doesn’t come out the other side – presumably it’s getting filtered/invalidated somewhere, but I can’t seem to find where?
