[Geoserver-devel] Problem with WMS map detail

I have a worldmap in a PostGreSQL database in a MultiPolygon column, when i
send the request to the wms
http://gandalf.unet.edu.ve:8080/siggengs/wms?REQUEST=GetMap&WIDTH=300&HEIGHT
=400&BBOX=90,180,-90,-180&LAYERS=siggen:worldmap&STYLES=normal&FORMAT=image/
png
with BBOX=90,180,-90,-180 only few poligons are shown, i think only show
the Geometry with only one Polygon.

Please visit the link and help me,
