[Users] GeoExt LayerContainer with checkbox

[Sarah Schuessler]

Hi,

if you get all layers from same server then you can use a gx_layer as nodeType afaik.

Hope this helped a little.

best regards
Sarah

Hi,

The problem of this code is that selecting all layers in the 
LayerContainer doesn't select the parent checkbox. Any idea?

Thanks
