Hi David,
the sequence generator implementation now only generate
id's for fields declared in the repository.
I think you got this NullPointerException, because SM get a
'null' field:
<snip SequenceManagerHelper>
public static String buildSequenceName(
PersistenceBroker brokerForClass, FieldDescriptor field)
{
48--->!!! ClassDescriptor cldTargetClass = field.getClassDescriptor();
String seqName = field.getSequenceName();
.....
</snip>
So check your code if the given FiledDescriptor wasn't null.
HTH
regards,
Armin
