  Normally, you'd edit the list of items such that you had a blank one with an empty value?

  There is a "first_option" parameter you can pass to your form field that will give you that empty option.

  Thank you for your answers!
  I don't want to add a "no value" record to the table.
  I used the "first_option" parameter, as suggested by admin, but i had to implement the "on_before_save" function to replace the "0" value to NULL. Otherwise, the "0" is saved.
  
  $fields['lugar_nacimiento_provincia_id']['first_option'] = array(0=>' ');
  
  Is there a better way to do that in order to avoid the on_before_save changes?
  
  Thanks!!

  Actually, you can just use:
  $fields['lugar_nacimiento_provincia_id']['first_option'] = 'Select one...';

  It saves "0" too instead of NULL value.

  If you look at the options on your select, is there a 0 value for the first option or an empty value=""?

  There is no value attribute for that option in the select but it keeps saving a "0".
  And no default value for that field in the db.

  What type of field is it in the database? If it's an int type field, an empty string is the equivalent to a "0". If you don't want a "0" then you'll need to set the default value to NULL. You may also need to add some code in an on_before_save model hook to convert empty strings to NULL values.

  Everything looks ok but it keeps saving "0".
  It's OK, it's not a big problem keeping the on_before_save hooks I implemented.
  Thanks for your help!
