dcaPicker not working

[mpitz]

The icon of the dcaPicker seems not to work:

Here is the code of the dca file:

$GLOBALS['TL_DCA']['tl_content']['fields']['footer_metalinks'] = array
(
    'label'                   => &$GLOBALS['TL_LANG']['tl_content']['footer_metalinks'],
    'explanation'             => &$GLOBALS['TL_LANG']['tl_content']['footer_metalinks'],
    'exclude'                 => true,
    'inputType'               => 'multiColumnWizard',
