That was what I thinked... But what if my object contains a Collection of
proxies that should be updated too?
And that proxies has a (proxied) reference to the main object?
This is the reason I've to put that line...
See sample repository.xml:
<class-descriptor
class="br.com.mgr.beans.BeanA"
proxy="dynamic"
schema="MGR"
table="TB_A">
<field-descriptor
name="id"
column="ID"
jdbc-type="VARCHAR"
primarykey="true"
autoincrement="false" />
<field-descriptor
name="description"
column="DS"
jdbc-type="VARCHAR" />
<collection-descriptor
name="allB"
collection-class="org.apache.ojb.broker.util.collections.RemovalAwareList"
element-class-ref="br.com.mgr.beans.BeanA"
proxy="true"
auto-update="true"
auto-delete="true">
<orderby name="id" sort="DESC"/>
<inverse-foreignkey
field-ref="idA"/>
</collection-descriptor>
</class-descriptor>
<class-descriptor
class="br.com.mgr.beans.BeanB"
proxy="dynamic"
schema="MGR"
table="TB_B">
<field-descriptor
name="idA"
column="ID_A"
jdbc-type="VARCHAR"
primarykey="true"
autoincrement="false" />
<field-descriptor
name="idB"
column="ID_B"
primarykey="true"
jdbc-type="VARCHAR" />
<field-descriptor
name="value"
column="VL"
jdbc-type="DOUBLE" />
<reference-descriptor
name="a"
proxy="true"
class-ref="br.com.mgr.beans.BeanA">
<foreignkey field-ref="idA"/>
</reference-descriptor>
</class-descriptor>
In this case, when assertFk is called, the beanB object is a proxy, that
cama from a collection proxy inside beanA, and beanA is not a proxy anymore.
This is the research I've done.
Maybe I'm wrong, but why my app works fine if I don't use proxies for the
collection? And why, when debugging, NetBeans shows that beanB in assertFk
IS a proxy? If the change I've done should not be there, then it should be
in other place - I don't know where. But it is needed. I'm using a
non-modified CVS HEAD obtained today (about 3 hours ago).
Please, double check it...

hi edson,
this may help, but afaik a proxy is always converted into a real object
before assertFkAssignment() is called.
see store()
// ProxyObjects only have to be updated if their real
subjects have been loaded
obj = ProxyHelper.getRealObjectIfMaterialized(obj);
