[OpenLayers-Users] OpenLayers passing query bounds in wrong
projection

Ok, I've been banging my head against this for a couple of days. I'm sure
I'm just missing something simple. My map is in epsg:900913, the WFS
request is passed to mapserver which hits a postGIS database containing a
grand total of 2 point features.
Code snippets follow:
---------------------------------------------
var options = {
projection: new OpenLayers.Projection("EPSG:900913"),
units: "m",
maxResolution: 156543.0339,
maxExtent: new OpenLayers.Bounds(
-20037508.34, -20037508.34,20037508.34, 20037508.34),
controls: [
new OpenLayers.Control.LayerSwitcher({'ascending':false}),
new OpenLayers.Control.MousePosition(),
new OpenLayers.Control.PanZoom(),
new OpenLayers.Control.ScaleLine()
]
};
var map = new OpenLayers.Map('map', options );
var tripdata = new OpenLayers.Layer.WMS( "Trips",
"http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apache/htdocs/gpshistory/test5.map",
{isbaselayer: 'true',layers: 'trippoints,tracks', format:
'image/png'});
var waypoints = new OpenLayers.Layer.WFS("Waypoints",
"http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apache/htdocs/gpshistory/test5.map",
{request: 'GetFeature', typename: 'waypoints', projection: new
OpenLayers.Projection("EPSG:4326")});
map.addLayers([ waypoints,tripdata ]);
-----------------------------------------------------
The Mapfile contains layers defined only as epsg:4326. However in the
MapServer error file, I can see the that bouding box being passed is still
in epsg:900913. Here is a line from the errorfile:
[Thu Mar 19 16:42:44 2009].203000 query_string_0_6:DECLARE mycursor BINARY
CURSOR FOR SELECT
asbinary(force_collection(force_2d(the_geom)),'NDR'),uniqueid::text from
waypoints WHERE the_geom && setSRID('BOX3D(1490115.87110093
5220415.61602237,1528334.38523667 5239524.87309024)'::BOX3D, 4326 )
What am I missing?
Thanks,
cj
