Language File strange js error

Alfred

Hi,

i switcht from inline Language:

"oLanguage": {
"sProcessing": "Bitte warten...",
"sLengthMenu": "MENU Einträge anzeigen",
....}}

to :

"language": {
"url": "./js/locales/dataTables.german.lang.json"
}

It is working if i load the page first. After a reload (F5) i get an JS Error...

Firebug says: TypeError: i[n] is undefined in jquery.dataTables.min.js (DataTables 1.10.5)

My fault?
