Hello.
I am newbie to GeoServer and OpenLayers.
I am trying to setup a WMS that consists of 6 layers of thematic maps on GeoServer. I tried to add LayerSwitched() to the code but the map just went blank. My question is: is it possible to add LayerSwitched for a Layer Group of WMSs? If no, is there another way to show 6 layers of thematic maps (somehow at the same time) on GeoServer?
Thanks in advance.

Sounds like a question for the OpenLayers list.

Hi Ammar,
WMS is a great tool for showing layers altogether.
To pinpoint your issue it will be usefull to have the part of the code you are using to load the layers into the map and to display the layerswitcher.
Can you please provide a little snippet?
Thank you

Hi,
as Russ Hore also pointend, it’s an OpenLayers question, here’s why:
I see you are using the GeoServer “OpenLayers Preview” as a base to build your map.
I highly discourage that, because that page has the only required tools to preview the selected layer.
If you want to start learning OpenLayers I recommend you this tutorial:
http://docs.openlayers.org/library/introduction.html
It’s a step-by-step tutorial, very practical.
The reason your map becomes blank it’s because the OpenLayers library provided with the Preview page doesn’t include the LayerSwitcher control.
Trying to load that Control breaks the code execution, preventing the loading of the map.
As you can see in the source code, there is a comment to warn you about that.
I hope this helps. Regards
