Hi!
How do I have to map the following configuration without superclass for :
ClassA with as field List<ClassC>
ClassB with as field List<ClassC>
in database :
+--------------+----------+
| objectA_id | ... |
+--------------+----------+
| 1 | ... |
| 2 | |
+--------------+----------+
+--------------+----------+
| objectB_id | ... |
+--------------+----------+
| 1 | ... |
+--------------+----------+
+--------------+----------+----------+----------+
| objectC_id | ... | class | id_FK |
+--------------+----------+----------+----------+
| 1 | | A | 1 |
| 2 | | B | 1 |
| 3 | | A | 2 |
| 4 | | A | 2 |
| 5 | | B | 1 |
| 6 | | A | 2 |
+--------------+----------+----------+----------+
Thanks!
