      While upgrading my own plugin to 3.1 I found several errors in Tag API:

      Error 1: If the tag collection is predefined in the db/tag.php (example), the "Manage tags" page throws an exception

      Coding error detected, it must be fixed by a programmer: Options for select element must contain an option for the specified value
      		 
       
      		 
      More information about this error
      		 
      Debug info:
      		 
      Error code: codingerror
      		 
      Stack trace:
      		 
       
      		 
          line 175 of /lib/classes/output/inplace_editable.php: coding_exception thrown
      		 
          line 56 of /tag/classes/output/tagareacollection.php: call to core\output\inplace_editable->set_type_select()

          line 188 of /tag/manage.php: call to core_tag_areas_table->__construct()

      Error 2: Specifying the tag callback as a static function in a class throws a fatal error

      'callback' => 'local_testtags_process::tags',

      Error 3: Again fatal error when upgrading plugin that used to add a form element 'tags' this way:

      $mform->addElement('tags', 'tags', get_string('tags'));
