range partitioning problem...

Hi!
(10.2.0.1, linux)
I've got an error (ORA-14037: partition bound of partition P_Y8_X1 is too high) when trying to partition my spatial table:

This is the first time I have tried to do partitioning at all so this is likely not a difficult problem. (No idea if this is the optimum partitioning but I can only test that if I can generate partitioned tables at all.) The idea here is to partition a spatial table such that each partition is a "tile" of my plane and to have a set of "infinite" partitions around the circumference of the square area (MinX=-150,MinY=-150,MaxX=150,MaxY=150). The first two parameters of the partitioning clause are supposed to make sure that all geometries spanning more than two tiles get inserted into the last partition (PLARGE).

Can anyone help me out?

Lots of Greetings and Thanks!
Volker
