I have a field in my notes table called ContactFK. (Integer,Nullable).  It's a foreign key to my contacts table. The contact is optional on a note.  I set the NULL value option in the BO Mapper to 'Use Nullable Generic'.

When I set my field to nothing I get an error 'Specified Cast is not valid' on the following line of code:

CType(component, CRMEntryBO).ContactFK = CType(Value, Nullable(Of System.Int32))

Is there something wrong with this setup?  I used Nullable generic a while back for a System.Double and it worked fine.

Thanks
