Can someone tell me why I get a "Cayenne validation" exception when I'm
trying to delete an object? Here is the stack trace ...
------------------------------------------------------------

... here is the code that generates the exception ...
------------------------------------------------------------
DAO class ...
public boolean deleteTopic(int topicId) throws DataAccessException {
Topic topic = loadTopic(topicId);
this.delete(topic);
return true;
}
DAO super class ...
public boolean delete(Object object) throws DataAccessException {
((CayenneDataObject)object).getDataContext().deleteObject((Persistent)object);
if (Transaction.getThreadTransaction() == null) {
((CayenneDataObject)object).getDataContext().commitChanges();
if (debug)
log.debug("CayenneDao >>> thread transaction not present
committing");
} else {
if (debug)
log.debug("CayenneDao >>> thread transaction present
commit deferred");
}
return true;
}
------------------------------------------------------------
... all my DAO's subclass a CayenneDao object.
It's not at all clear to me why validation happens on a delete event ???
thanks in advance.
