[Gvsig_english] Problems using geoBD with Oracle layer

[Wolfgang Qual]

Hi list,
I just had the possibility to test geoBD-extension with an Oracle Spatial Connection.
I could connect to the Oracle Database, all layers appear in the GeoBD-dialogue box. 
However, when trying to activate one of them, the error message appears:
"Error while getting valid geometry fields: no spatial indexes found on geometry field of table [tablename]".
This is strange, as I see the column "GEOM" in the list of columns of this table. Is there a reason, why this column is not recognised? Geom is of type MDSYS.SDO_GEOMETRY.

I would be grateful for any comments!
Best, 
Wolfgang
