As I suspected this did not work. How would the container know the coulmn and
the type to apply the discriminator value to if you omit the
@DiscriminatorColumn?
It seems to be complaining about a property named "connected". My entity has
no such property?
I see many examples like what I am trying to do yet I cannot get mine to work.
If I leave out @DiscriminatorColumn
I get:
