It fails when retrieving data from the database, when trying to retrieve the data from the database it throws an exception with:

        Conversion not valid from 'System.DateTime' to 'System.Nullable`1[[System.DateTime, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]'.

It worked fine with 4.7.0 but I don't know why it has trouble with the Nullable(Of DateTime) now.

Any solutions? am I doing something wrong?

I need help please, it crashes when retrieving a datetime field from the database that allows null value when mapping it to the field of the info class that is of type Nullable(Of datetime).

It worked fine on version 4.7.0 of dotnetnuke but it crashes in dnn 4.8.0.

Maybe I'm doing something wrong, but I feel it's a bug in the CBO class of the new dotnetnuke.

Is this a know issue? any workaround? fix?

Please help, it's important.

AFAIK nullable datatypes are not supported by MS DAAB, which is used for data access.

But it worked fine in dnn 4.7.0, how should I do it then in 4.8.0?
