Here is excerpt for the collection-descriptor :
<collection-descriptor
name="bx"
collection-class="org.apache.ojb.broker.util.collections.ManageableArrayList"
element-class-ref="br.com.mgr.b.f.Bx"
indirection-table="RL_C_BX"
proxy="true"
auto-update="true"
auto-delete="true">
<fk-pointing-to-this-class column="CC"/>
<fk-pointing-to-this-class column="CH"/>
<fk-pointing-to-element-class column="T"/>
<fk-pointing-to-element-class column="P"/>
<fk-pointing-to-element-class column="BX"/>
</collection-descriptor>
As you can see, the fk-pointing-to-this-class uses 2 fields, and the
fk-pointing-to-element-class uses 3 fields.
I don't have a test case (but I think armin has one). The collection-descriptor I show
here was takes directly from my production code.
Best regards,
Edson Richter

MtoNCollectionPrefetcher.buildPrefetchCriteriaMultipleKeys(MtoNCollectionPrefetcher.java:338)
hi armin, edson,
it looks like the number of pk-fields and the number of columns in the
indirection table pointing to the m-side class are not the same.
could you please send me the testcase ?
