Hi,

I have two classess, A and B, where A extends B. I use single-table inheritance with discriminator values, and it generally works OK. Now, in both classes I use custom-type fields which map to the same db column as Oracle's XMLType (via JiBX mapping - but it doesn't matter)... The thing is having the same column declared in both A and B.

So:
class A has field "AXml xml;"
class B has field "BXml xml;"

additionally, to have this configuration working in Java, BXml must extend AXml. Without it, compilation error occurs, which is quite understandable.

I try to add these fields mappings to A.hbm.xml and B.hbm.xml, but it doesn't work... Hibernate says that both fields access the same database column. Of course using other columns - works, but that's not what I need.

It would be nice to have this inheritance working. I know it's a rare situation, but a good-looking one from OO point of view, when using custom types. Is there any way to achieve it? Or should I register CR?

Greets,
Adam
