Dereference list

This project enables list fields to populate their allowed values from a field on a referenced entity. For example, the Project issue tracking module reads the allowed values of the component list field on issue nodes from a field on a project (which can be found through an entityreference).

Note: this module requires Drupal core 7.14 or later, since it depends on the changes introduced at #1541792: Enable dynamic allowed list values function with additional context.

Here's an example of how to use it:

  $field = array(
    'cardinality' => '1',
    'field_name' => 'field_issue_component',
    'module' => 'list',
    'settings' => array(
      'allowed_values_function' => 'dereference_list_allowed_list_values',
      'entityreference_field' => 'field_project',
      'dereferenced_field' => 'field_project_components',
    ),
    'type' => 'list_text',
  );

This module was written by chx alone, don't blame bdragon for it.
