I checked that our repository_user file does not contain auto_XXX for an
reference-desc and collection-desc, are these mandatory and could be cause
of problems?
It seems that OJB can't find the Question object in intern object
registry using it's Identity. OJB detect that the object no longer
exists in the 1:n reference and try to remove the Question object.
To enable cascading delete it's mandatory to set auto-delete="object".

Could you please post the used source or pseudo code?

Hi,
We are using same table for different subclasses using a varchar column
and define ojbConcreteClass to find the actual class.
When we try to delete a object in a relationship , i see an error
"unregistered object for delete:" . I saw a previous forum question,
suggestion for the error and implemented writing locks for all objects in
transaction, but we still have the error.
In our case we have an object AssessmentGroup and an object Question in
1:n relationship ( Question has different types of questions /subclasses
in a same table differentiated with classidentity column of the table).
This error occurs when we delete a MultipleChoice sublclass of Question
and remove its relationship with AssessmentGroup.
Detailed logs shows we are locking
AssessmentGroup,MultipleChoice(subclass) before delete,
but the exception shows even when we are writing
db.deletePersistent(multiplechoiceobj) , it is trying to delete base class
internally. Do you think this is expected behaviour? Are we supposed to
lock base class inspite of knowing which exact class we are deleting?
The exception is
org.apache.ojb.odmg.Image$ImageException: Unexpected behaviour,
unregistered object to delete:
com.tk20.bo.evaluationinstrument.Question{100007f1388e5e10fe3fa0849-7ff1},
main object is
com.tk20.bo.template.AssessmentGroup{100007f1388e5e10fe3fa0849-7ff3},
envelope object is
