Hi Trung, nice debugging! :)
> Anyway, we realized that we got this exception whenever the sdeLayer (that
we got from the ArcSDE data) has this SeExtent value: sdeLayer.SeExtent =
(9.999E35,9.999E35,-9.999E35,-9.999E35).
This is strange, since the SeExtent is meant to be minx,miny,maxx,maxy but
yours seems to be maxx,maxy,minx,miny.
Does the range you're using actually belong to a real crs? it seems to be too
wide. How was the arcsde layer created, and how did you set the bounds, crs
and index grid sizes?
