Inserts into Partitioned Table fail with Ora-14400

We're inserting records via SQL*Loader into a 9.2.0.6.

The table is Range Partitioned.
The last partition is defined as Maxvalue.

If you have a maxvalue partition it should not be possible to see

Record 8: Rejected - Error on table LEAVES. ORA-14400: inserted partition key does not map to any partition

But every record fails.

MaxValue should be just like an "else", right? And the docs say that Nulls go to maxvalue partitions.

Either the value is less than some partition we defined or less than maxvalue but it's not unmappable.

What am I missing?

Thanks,

Mark Brady
