Hi,

there is the following object structure (all custom types)

(i.e. AClass has a field embeddedB which has a field CClass embeddedC).

There should be a reference to CClass embeddedC in AClass.
This shall be done via BClass' reference to CClass with the following simple formula (in AClass):


This however results in an

exception.

In case embeddedC is not a custom type but e.g. a String, this works well using the slightly modified formula


Is this a bug or is it not possible at all to reference custom types using formulas?

According to http://docs.jboss.org/hibernate/core/3. ... pping.html (search for "formula (optional): an SQL expression that defines the value for a computed foreign key.") to me it seems possible.

I'd be glad for receiving answers.
Thank you

Can somebody comment on this?
This would help me to decide whether I could hope for a potentially very neat solution to my problem or whether I should opt for a different approach.

Thanks a lot
