get dca_value for tl_member

[zonky2]

I`ll get out two fields of tl_member country and own field lable from select type - both output is only the key

country: {{dca_value::tl_member::country::de}}

if I debug at https://github.com/codefog/contao-haste/blob/master/library/Haste/Util/Format.php#L138 and get the $arrField:

array:9 [▼
  "label" => & array:2 [▼
    0 => "Land"
    1 => "Bitte wählen Sie ein Land."
  ]
  "exclude" => true
  "filter" => true
  "sorting" => true
  "inputType" => "select"
  "eval" => array:6 [▶]
  "options_callback" => Closure {#1427 ▶}
  "sql" => "varchar(2) NOT NULL default ''"
  "name" => "country"
]

own field

$GLOBALS['TL_DCA']['tl_member']['fields']['legal_form'] = array
(
  'label'                   => &$GLOBALS['TL_LANG']['tl_member']['legal_form'],
  'exclude'                 => true,
  'inputType'               => 'select',
  'options'                 => array('ek', 'gmbhco', 'gmbh', 'gbr', 'ag', 'ohg', 'ug', 'kg', 'gmbhco', 'ev', 'other'),
  'reference'               => &$GLOBALS['TL_LANG']['tl_member']['legal_form']['forms'],
  'eval'                    => array('includeBlankOption'=>true, 'feEditable'=>true, 'feViewable'=>true, 'feGroup'=>'personal', 'tl_class'=>'w50'),
  'sql'                     => "varchar(32) NOT NULL default ''"
);

and {{dca_value::tl_member::legal_form::gmbh}}

array:8 [▼
  "label" => & array:3 [▼
    0 => "Rechtsform der Betreibergesellschaft"
    1 => ""
    "forms" => array:10 [▶]
  ]
  "exclude" => true
  "inputType" => "select"
  "options" => array:11 [▶]
  "reference" => null
  "eval" => array:5 [▶]
  "sql" => "varchar(32) NOT NULL default ''"
  "name" => "legal_form"
]
