Re: SequenceManager trouble with rc3

[David Forslund]

I'm having some problems moving from 0.9.8 in the SequenceManager.   I have 
a polymorphic class ObservationValue_ that
has multiple <extent-class>.   I have a primary key "valueId" which I try 
to increment with the call 
broker.serviceSequenceManager().getUniqueValue(field);
This call fails with a NullPointerExdeption.  It works in another case 
where the class isn't polymorphic.  I had a work around
in 0.9.8 to handle this case:
       /**
        try {
        // work around problem in OJB 0.9.8
            ClassDescriptor cld = broker.getClassDescriptor(clazz);
            if ( (cld.isAbstract() || cld.isInterface()) && cld.isExtent())
               clazz = (Class)cld.getExtentClasses().get(0);
            return broker.getUniqueId(clazz, fieldName);
        } catch (org.apache.ojb.broker.PersistenceBrokerException e) {
            cat.error("Can't get ID from broker: " + clazz.getName() + " " 
+ fieldName, e);

            // System.exit(1);
            return 0;
        }
         */
but I thought this should have been fixed.  The method getUniqueId isn't 
any more.
I did make a change along the lines above to redefine clazz and it seems to 
work.
Is this the way I should do it, or am I missing a new call somewhere?
