[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
