[OpenLayers-Users] WMS-layer: BBOX and SRS not being detected

Dear list,
Today I set up a MapServer WMS service. The service seems to work just fine,
as I tested it with QGIS. Even the SRS is recognized automatically:
EPSG:28992 (Dutch CS).
At the bottom of this message, I copy/pasted the GetCapabilites-response.
The bit of JavaScript used to load the OpenLayers control + map + layer, is
classical:
============
var map, layer;
function init(){
map = new OpenLayers.Map( 'map' );
layer = new OpenLayers.Layer.WMS( "OpenLayers WMS", "
http://localhost/mapserv?map=/var/www/geo/binnenstad_wms.map&", { layers
: 'pgn_verwachting' }, { units : 'm', projection : new
OpenLayers.Projection("EPSG:28992"), singleTile : true, buffer : 0, ratio :
1 } );
============
In my browser, OpenLayers does load nicely (zoom and pan tools become
available in the upper right corner of an empty map-div) and then does the
following GET to fetch that single tile:
http://localhost/mapserv?map=/var/www/geo/binnenstad_wms.map&LAYERS=pgn_verwachting&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A28992&BBOX=-281.25,-210.9375,281.25,210.9375&WIDTH=800&HEIGHT=600
I don't see how I can get the BBOX parameter right... What am I missing?
When I edit the above URL, it works just fine, obviously...
And shouldn't the SRS be detected automatically as well?
Hints are much appreciated!
Kind regards,
Rob
