SQL Developer 2.1 (final but also RC and EA) - Spatial index creation error
If you have a table with a column of type SDO_GEOMETRY, and you use the edit table editor to insert a new spatial index to the column, you get an error that say that the column type (SDO_GEOMETRY) is not suitable for a text index (who ask you for text index then :P).
This problem was present from the first version of SQL developer 2.1, and still present in the final version!!!
Very annoying!
