inherit problem

[Carles Duque <cd...@eic.es>]

Hello!!
 
I have a problem witth retrieve two classes in a two tables.
Classes: A and B. B estends A.
 
When I have one class (example: A) I see if Id (getId()) is null. If its true, I do "select MAX" and I assing to class (setId()). This work ok, always.
In the new case (A and B), when I retrieve a class B, I do "select MAX", assign id, but returns SQLException, because ID is null.
 
Is possible that if you put "auto-retrieve=true", you must use auto-increment?? Its possible another solution?
 
Thanks!!!

Hi,

auto-retrieve does not require auto-increment to be set.

You likely made a misstake in your class-definitions and or repository 
declarations.
