-------------------------------------

Andy, many Thanks for the fix. 

One problem with the fix we have is, that there is a NullPointerException in line 1259 of KFListStore for classes without order-mapped-by. It looks like orderMapping != null and orderMapping.getFieldMetaData() == null. Can you please have a look on it?

I have tested this with the SNAPSHOTS from 28. and 29. November.
