I’m not sure if this is what you need but this works for me at the tree leaf
level.
nodeType: "gx_layer",
layer : layerStore['LGATE-008'],
text : layerStore['LGATE-008'],
isLeaf : true,
disabled: disablePublic
,id : layerStore['LGATE-008']
I set disablePublic to true if the service is broken which I test at load time.
If I needed to do this based on scale during the processing I would probably
setup an OL zoomend event and reset this via the layer Id and this node Id.
Hope that helps.

Subject: [Users] Disable treenode according to scale
Hi,
this code turns off the layer "layer_wea_wms" when I zoom out by more than
zoomlevel 8. What I would actually like to do is complete disable the treenode
as well so that it is impossible to make it visible.
I have tried to get a reference to the treenodes by name, but I cannot return
the object. The treenodes are loaded automatically using the code below
Does anyone know how I could disable the node?
thanks,
Rob
// TREE
var layerList = new Ext.tree.TreeNode({
text: "Kartenebene",
expanded: true
});
layerRoot.appendChild(new GeoExt.tree.BaseLayerContainer({
text: "Hintergrundkarten",
map: map,
expanded: true
}));
layerRoot.appendChild(new GeoExt.tree.OverlayLayerContainer({
text: "Themen",
map: map,
expanded: true
}));
var layerTree = new Ext.tree.TreePanel({
title: "Karteninhalte",
region: "center",
root: layerRoot,
enableDD: true,
collapsible: true,
height: 200,
expanded: true
});
// Scale dependant layer
map.events.on({ "zoomend": function (e) {
if (this.getZoom() > 9) {
layer_wea_wms.setVisibility(true);
}
else {
layer_wea_wms.setVisibility(false);
}
}//end function (e)
}); //end map.events.on
