[mapguide-users] Connecting to WMS

Hi Kenneth,
I explored the error log.
The problem is that coordinate systems do not match BUT :

1. The error log says
/The coordinate system (*EPSG:32633*) of layer RissaWMSLayer1 cannot be 
different than the coordinate system (*EPSG:32632*) of the map
/2. The wms layer is configured to use /*EPSG:32632 */- in my config.xml 
it is written
/      <RasterDefinition name="Image">
        <Layer name="VERANDA">
/3. The service supports this coordinate system - in GetCapabilities 
document I have

<BoundingBox SRS="EPSG:32633" minx="218329.98786561" 
miny="7160648.90075887" maxx="305197.974972341" maxy="7041546.39019898"/>
<BoundingBox SRS="**EPSG:32632" minx="506720" miny="7147644" 
maxx="604333" maxy="7037305"/>
<BoundingBox SRS="EPSG:32634" minx="-68103.0343048812" 
miny="7200948.9760428" maxx="7352.92691530631" maxy="7073836.91252369"/>
<BoundingBox SRS="EPSG:9804" minx="1017422.41132931" 
miny="9427477.01214373" maxx="1234782.60719126" maxy="9172903.66920839"/>

So, I want the map and WMS layer to be in coordinate system *32632*, the 
Feature source is configured to use this coordinate system, the service 
supports it, but still the server sends the output in *32633.*
Can you spot my mistake ?

Best regards : Stefan Dalakov
