Simple WMS layer does not add STYLES to the URL

mapserver-bot commented 12 years ago

Reporter: woodbri@swoodbridge.com Date: 2006/11/28 - 04:15 Trac URL: http://trac.osgeo.org/mapserver/ticket/1974

In mapwmslayer.c:400 pszStyle can be set to ""
At mapwmslayer.c:424 STYLES is only add if (strlen(pszStyle) > 0)

Here is a simple mapfile the reproduces the problem:

MAP

  END

  END

    END
  END

Author: jmckenna Date: 2007/07/04 - 20:02 i have also hit this same issue, with MapServer 4.10.2

Author: jmckenna Date: 2007/07/05 - 23:28 i come across this only when accessing an arcIMS layer.

Author: woodbri Date: 2007/07/05 - 23:37 I found this using OpenLayers so I think it is a more general issues.

Author: tomkralidis Date: 2008/06/04 - 04:00 Steve: I believe #1088 may have fixed this. Can you verify?

Author: woodbri Date: 2008/06/24 - 16:51 Tom,

I get the following. The WMS connection timed out so I'm not sure if this hits the code or not. Sorry, I have been swamped lately. If you have another WMS site handy and you are happy with the results, then I'm good also. I can't remember what I was doing 2 years ago when I reported this, but I'm glad you have picked it up and done something with it.

Thanks, -Steve

I get an image back as expected. STYLES seems to be passed correctly.

Steve: any chance you can quickly test and verify?
