SDO_GEOR.importFrom : Unable to render RenderedOp for this operation

Question

Contributors,
I have trouble in loading a persistent LOB into a georaster :
- I use sdo_geor.getRasterSubset to get whole cells (512x512) of band 0 of a 8BIT_U georaster, into a BLOB
- dbms_lob.getLength of the blob gives me correct length : 262144 (=512x512)
- i stored this blob into a persistent LOB (LOB in table)
- just to check, i did dbms_lob.getLength for the BLOB column. gives me 262144
- but when i used SDO_GEOR.importFrom to load the BLOB from the blob table into the georaster table, error occured :
ERROR at line 1:
ORA-13464: error loading GeoRaster data: - Unable to render RenderedOp for this operation.

All right now am in 11g; after some error in installing 11g, failure in data moving when upgrading from 10gR2 to 11gR1 so i lost all my data (did not backup coz little space left).
Then i decided to get rid all the installed 11g and 10gR2, cleaning up the registry keys, for clean installation of 11g.
The 11g is now installed. I didnot have data backup but for georaster backup i can rely on the raster file and table creation sql i stored in text files. When i use the GeoRasterViewer tool (now version 11) for importing these raster files, the "OK" button in 'Import to DB' dialog does not give me anything. It does not works. Nothing loaded. The raster file is 8 bit TIFF, 512 rows x 512 cols x 15 layers. (i tried different images but no luck).
Here is my table definition :
CREATE TABLE multilayer
(image_id NUMBER,
raster_description VARCHAR2(70),
image SDO_GEORASTER);
CREATE TABLE multilayer_RDT OF SDO_RASTER
(PRIMARY KEY (rasterID, pyramidLevel, bandBlockNumber,
rowBlockNumber, columnBlockNumber));
INSERT INTO multilayer
VALUES(1, 'Raster trial KALISYA! 512x512x15', MDSYS.SDO_GEOR.init('multilayer_rdt', 1));
(the createDMLtrigger is not necessary anymore in 11g, right?)Another problem is : i created a georaster table for raster of 4 rows x 4 cols x 4 layers, with my specific value for every cells (64 cells all) specified by .changeCellValue. Here is : CREATE TABLE four (image_ID NUMBER, description VARCHAR2(50), image SDO_GEORASTER);     
CREATE TABLE four_RDT OF SDO_RASTER (PRIMARY KEY (rasterID, pyramidLevel, bandBlockNumber,rowBlockNumber, columnBlockNumber));
INSERT INTO four VALUES (
1,'A 4rows x 4columns x 4bands image',
sdo_geor.createBlank(
21001,                              --raster type 3D
SDO_NUMBER_ARRAY(0,0,0),     --origin
SDO_NUMBER_ARRAY(4,4,4),      --dimension sizes 4x4x4 cells cube
0,                                    --cell values
'four_rdt', 1)                    --RDT and rasterID
DECLARE
gr sdo_georaster;
BEGIN
SELECT image INTO gr FROM four WHERE image_id=1 FOR UPDATE;
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(0,0,0,0),'0',1);
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(0,1,0,1),'0',2);
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(0,2,0,2),'0',3);
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(0,3,0,3),'0',4);
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(3,2,3,2),'3',63);
SDO_GEOR.changeCellValue(gr,SDO_NUMBER_ARRAY(3,3,3,3),'3',64);
UPDATE four SET image=gr WHERE image_id=1;
COMMIT;
END;
/The console says everything ok but GeoRaster viewer does not show the data AND metadata (metadata tab is blank white). In console i can get the .getCellValue as well (see the value of cell at 4th row 4th col 4th layer is 64).
select sdo_geor.getCellValue(image,0,3,3,3) from four where image_id=1;
SDO_GEOR.GETCELLVALUE(IMAGE,0,3,3,3)
                                  64? These were simple and smooth in 10gR2 but i found them weird in 11g. any suggestion ? i tried validate but no luck as well.
