Completly with you. But as long as the ObjectStorage does only contains 
Objects with EnableFields==TRUE you cannot rely on this in the 
storageBackend and "delete all relations and rebuild them afterwards 
with info from objectstorage".

The ObjectStorage currently is only a "view" on the data, hiding the 
hidden records, but the storagebackend should work on real data, not on 
a view.

CHanging the ObjectStorage might be quite complex, there fore I am just 
adapting the "persistObjectStorage" method.
