Hi,
your mapping seems ok. Could you post the generated class-descriptor for AddressTypeBO and AddressBO too?
there were send -> point 3) repository.xml - this only fragment of repository.xml, only class-descriptor for AddressTypeBO and AddressBO
oh, sorry I overlooked this - too long mail ;-)
The problem could be caused by the extents mapping of the BO object:
>>> <class-descriptor
>>> class="com.chw.crm.BusinessObject.BO"
>>>
>>>>
>>> <extent-class class-ref="com.chw.crm.BusinessObject.AddressBO"/>
>>> <extent-class class-ref="com.chw.crm.BusinessObject.AddressTypeBO"/>
>>> </class-descriptor>
Assume BO class is only a base object for your business classes and you never want to query "give all BO objects". In this case you shouldn't declare AddressBO and AddressTypeBO as extent of BO.
Try to remove this entry and run your test again.
If this solve your problem try determine-extents="false" in AddressBO and AddressTypeBO to suppress generation of extent mapping.
Did you try without the 'id' attribute (it's optional) set? Which version do you use?
ojb 1rc7, oracle 9i, tomcat 5, struts
If you get problems caused by xdoclet-modul try latest version of the xdoclet-ojb-modul.jar (or use the version shipped with OJB 1.0).

I'm using ojb since yestarday and I experience some problems ...
when I use ojb for one class which takes date from one table everything is ok, the problem begins when I have object o1 of a type AddressBO which has an object o2 of a type AddressTypeBO and I want to take o1 and of course have o2 filled.
And of course, when I want to do this I get error.
Any help is appreciated :)
I attached : 1) errorr description 2) java classes 3) repository.xml
1) I get this type of error :
