[Users] Different layer containers in a single layer tree

[Christian Mayer]

Hi Luis,

I think you mixed up two things: instead of using a direct instanciation
of the GeoExt.tree.LayerContainer AND giving an nodeType in both cases
you should use a declaration with only a nodeType like this

var baseLayerList = {
    "nodeType": "gx_baselayercontainer"
       ...
};

The same with the overlay container.


The things with the "additional node in the tree without a name":  This
is the so called root node. By giving your TreePanel instance the config
option

rootVisible: false


the root folder could be hidden.

More infos could be found here:

Best regards,
Chris
