Post by halley73to » Fri 06 Nov 2009 10:27

I've installed version 5.35 beta.

Now when i load a DataGrid with a columns that display a relation to another entity like DSettori.Descrizione of entity DMagazzini, Visual Studio give me an exception of this type:

System.NullReferenceException non è stata gestita dal codice utente
