Not accepting null in foreign key attribute.

[Devanand Chahal]

I have a relation between two classes and the foreign key in one class is made nullable (by using "?"  after the name of foreign key variable). In the data table its also accepting null value. I have forward mapping of this persistent foreign key to the foreign key in the table (in table this foreign key is nullable). It is giving me runtime error when it comes on the declaration of that variable.

Any workaround to this problem would be highly appreciated ..............

Hello Devanand Chahal,

 Can you provide more information about the error you get at runtime - error message, stack trace etc.
If possible you could also send us the app.config file so that we can have  a closer look at your mapping. This would help in resolving the problem sooner.

All the best,
