[support] Drupal 7: How to set values (allowed_values) for field (select) dynamically (from module)?

Hi, I now about hook_form_alter() for modification form elements, but i have bad feeling use arrays like: $form['profile_main']['field_year_of_graduation'][LANGUAGE_NONE][0] I think sometimes can be LANGUAGE_NONE index changed and then my code not work. Is there better way for set allowed_values dynamically or i need create my custom field? Havran -- Juraj Chlebec aka Havran http://www.svoji.sk
