Uable to WFS Insert into Oracle DataStore

In GeoServer release 1.2.0-rc1. Was unable to perform a WFS insert into an Oracle Spatial datastore. GetCapabilties, DescribeFeatureType, GetFeature and Update Transaction all work okay.

Error Message displayed in the console is:

110676 [WARNING] org.vfny.geoserver.servlets.AbstractService - service exception while executing request: org.geotools.data.DataSourceException: Row adding failed.

In order to duplicate, the other environment set-up is as follows:

Spatial Table Creation Script

CREATE TABLE TEST_WFS
(
ID NUMBER NOT NULL,
NAME VARCHAR2(100 BYTE) NOT NULL,
EXTENT MDSYS.SDO_GEOMETRY,
DESCRIPTION VARCHAR2(1000 BYTE)
);

CREATE UNIQUE INDEX TEST_WFS_PK ON TEST_WFS(ID);

ALTER TABLE TEST_WFS ADD (
CONSTRAINT TEST_WFS_PK PRIMARY KEY (ID));

SDO Metadata Entry

INSERT INTO USER_SDO_GEOM_METADATA
(TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES('TEST_WFS' , 'EXTENT',
MDSYS.SDO_DIM_ARRAY(MDSYS.SDO_DIM_ELEMENT
('longitude', -180, 180, 0.000005),
MDSYS.SDO_DIM_ELEMENT
('latitude', -90, 90, 0.000005)),
8307);
