Thread:Extension talk:Semantic Forms Inputs/datepicker with german user localisation doesn't work correctly

Hi all! First, a big big thank to all who lets live this great software! And sorry for my english. As a rather unexperimented admin of a unfortunately non-public smw-wiki I don't now where to tune for this problem: The datepicker popup let me choose a date, but it fills in the form-field in a strange way: "TT.November.JJ" instead of "31/10/2012". The saved page contain also the defective string. When I edit a page witch contains already a correct date-string with the datepicker oder the datetimepicker-form, it appears also wrong. But this occurs only if the Language in "my preferences" is set to German. So, English and French works well. See the screenshot on. Contrary, the timpicker-form works well for all languages. This behaviour occurs only since the last upgrading of some extensions, but I don't now exactly of which one. Actually, this is our installation:. Thanks for help!
