Sylvain, thanks.
Is there anything I can do except waiting for a fix? Could I do something to my data? Or data model? I moved to 2.0.3 because I think I experienced missing rows in 2.0.1 paging - is this related to the 2.0.3 bug? Meaning: going back to 2.0.1 will fix the exception, but leave me with the faulty situation the assertion is there to detect?
