[mapserver-users] Cascading Legend with selected Style

[Berger, Cora]

Hello everybody,
I'm using a WMS as a layer with Mapserver 7. The source WMS is available in 3 different styles. I want my WMS to display the style called "SW", so I add  	 "wms_style"  "SW" 	to my layers METADATA, which works fine. 
If I try to add a legend to this layer I get problems. 

I tried this
  
"wms_style"              "SW"
  "wms_style__legendurl_href" "example-url"
  "wms_style__legendurl_width" "531"
  "wms_style__legendurl_height" "769"
  "wms_style__legendurl_format" "image/png" 
  "wms_feature_info_mime_type" "text/html"

And this

  "wms_style"              "SW"
  "wms_style_SW_legendurl_href" "example-url"
  "wms_style_SW_legendurl_width" "531"
  "wms_style_SW_legendurl_height" "769"
  "wms_style_SW_legendurl_format" "image/png" 
  "wms_feature_info_mime_type" "text/html"

Nothing works. The legend gets displayed, if I leave the "wms_style"-tag empty:

"wms_style"              ""
  "wms_style__legendurl_href" "example-url"
  "wms_style__legendurl_width" "531"
  "wms_style__legendurl_height" "769"
  "wms_style__legendurl_format" "image/png" 
  "wms_feature_info_mime_type" "text/html"

But now the mapimage gets displayed with the default-style, which is in color and not in black and white (SW), as I want it to be. 

The error-message for the 2 examples above is: msWMSLoadGetMapParams(): WMS server error. Style (SW) not defined on layer.


Any ideas?

Thanks!
