First thanks for your answer! I don't have many experience with Geoserver, so I have a question: In this field "default WMS path" do I have to type in numbers? Or how can geoserver identify the position? Can you give me a small example?
Kathrin ---------------------------------------------------------------------------- Hi! A tip that may help: maybe there is an easier way to do what you want. You can create a treePanel by using the "GeoExt.tree.WMSCapabilitiesLoader" class. Then, in GeoServer, you can fill in the "default WMS path" field of each layer: http://docs.geoserver.org/stable/en/user/webadmin/data/layers.html This field allows GeoServer to create a hierarchy in the WMS Capabilities document of your GeoServer. Then, this hierarchy is identified by the treePanel, that creates automatically themes and sub-themes.
