[Users] GeoExt Legend Tree and base layers ?

[Alexandre Dube]

Hi,

   I'm not sure about the origin of your issue, but looking at the 
following non-official ux might help you find it (since I managed to do 
that) :
http://dev.geoext.org/sandbox/mapgears/geoext.ux/ux/LayerTreeBuilder/examples/tree-builder.html

I hope this helps,

Alexandre
