contao/import — Issue #2247: DC_Table.php - Header Fields, references not working

How to generate this bug:

The format field in tl_form.php is defined as SELECT, using a language reference and helpwizard=>true as follows

```
'format' => array
(
'label' => &$GLOBALS['TL_LANG']['tl_form']['format'],
'default' => 'raw',
'exclude' => true,
'inputType' => 'select',
'options' => array('raw', 'xml', 'csv', 'email'),
'reference' => &$GLOBALS['TL_LANG']['tl_form'],
'eval' => array('helpwizard'=>true, 'tl_class'=>'w50')
),
```

The corresponding language reference is an array (to generate the HELP text in the Helpwizard pop-up).

```
$GLOBALS['TL_LANG']['tl_form']['raw'] = array('Raw data', 'The form data will be sent as plain text message with each field in a new line.');
$GLOBALS['TL_LANG']['tl_form']['xml'] = array('XML file', 'The form data will be attached to the e-mail as an XML file.');
$GLOBALS['TL_LANG']['tl_form']['csv'] = array('CSV file', 'The form data will be attached to the e-mail as a CSV file.');
$GLOBALS['TL_LANG']['tl_form']['email'] = array('E-mail', 'Ignores all fields except email, subject, message and cc (carbon copy) and sends the form data like it had been sent from a mail client. File uploads are allowed.');
```

This all works, EXCEPT, when you add this field to the Child Table, tl_form_field.php in the HEADER section of the child DCA.

```
$GLOBALS['TL_DCA']['tl_form_field']['list']['sorting']['headerFields'][] = 'format';
```

This is the error it generates, because you didn't take into account in the parent-child view, that the header view will need to take awareness of the array() in the language file, instead of just checking for strlen() -- if it's a string.

```
Warning: strlen() expects parameter 1 to be string, array given in /Library/WebServer/Documents/demo/system/drivers/DC_Table.php on line 3295
