hi claudio,
if the class CategoriesDescription has 2 pks then those 2 pks must be present in
the indirectiontable as it always must contain the sum of the pks of the
connected classes. either you add the languageId to fk-pointing-to-element-class
or you languageId must not be defined as pk.

Hi All,
i just updated to OJB_BRANCH_1_0. Now i have some Problems
with M:N mappings.
(The categories_description has two primarkeys!!)
I always get an exception when i try to get the CategoriesDesctiption
from the Product.
My Class-Descriptors:
jdbc-type="INTEGER"
nullable="false"
length="11"/>
primarykey="true"
jdbc-type="INTEGER"
nullable="false"
length="11"/>
nullable="false"
length="11"
indexed="true"/>
The Exception
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)
