i have the following class hierarchy
A
B:A
C:A

can i do a "select from A where id=xxxx" ?
everytime i try to do it i get an "object was not of the specified sublcass" error.

everything else is working fine. i can do all crud operations on B and C.

Please post your mapping(s) and code please. It is really the good idea to follow H forum suggested template.

I've seen that error when my base class is abstract and has an abstract method. This is, as far as I know, a limitation of the DynamicProxy.

Removing abstract methods fixes the problem for me.

This might not be your problem, but it's worth a shot!

Cheers,

Symon.

Hi, I was dealing the same problem long time ago, the cause was "char" type of the discriminator column (using varchar and trimming trailing spaces solved the problem)
