Wrong weekday for german date format

Hey guys,

I found a bug when working on a listgrid with date fields and german date format. When grouping the records by day, the weekdays will be wrong (moved one day, e.g. monday the 16 th becomes sunday the 16 th). For formatting the dates I used your library “/isomorphic/locales/frameworkMessages_de.properties”.

Following two screenshots, one with default date format and the otherwith german date format.

German date format:


This issue is reproducable in all current browsers (Chrome, Firefox & IE) and your latest nightly build SmartClient_v100p_2015-02-18.

Best Regards
