[Users] [TreeConfig][LayerNode.js] getVisibility is not a function

[antoniofacno]

Hello,

I'm still fighting with TreeMenu panel. This is my code written from the
ground:

         var lindes = new OpenLayers.Layer.WMS(
             "Lindes",
             "http://getcloud.info:8080/geoserver/wms",
            {
                 layers: "lindes",
                 format: "image/png",
                 transparent:true
             },
             {isBaseLayer: true, singleTile: true, visibility: true}
         );

         var catastro = new OpenLayers.Layer.WMS(
             "Base",
             "http://getcloud.info:8080/geoserver/wms",
            {
                 layers: "ao:Catastro",
                 format: "image/png",
                 transparent:true
             },
             {isBaseLayer: true, singleTile: true, visibility: true}
         );

         var treeMenu = [
         {
                 id:'1',
                 text: 'Base',
                 leaf: false,
                 children: [
                         {id:'11', nodeType: "gx_layer", layer:
"lindes", leaf:true},
                         {id:'12', nodeType: "gx_layer", layer:
"catastro", leaf:true}
                 ]
         }
         ]

         // create the tree with the configuration from above
         tree = new Ext.tree.TreePanel({
             border: true,
             region: "west",
             title: "Capas",
             width: 200,
             split: true,
             collapsible: true,
             expanded: true,
             root: {
                 nodeType: "async",
                 text: "AgroOffice",
                 children: treeMenu
             }
         });

I can open AgroOffice root, but when trying to open the Base Group the
console error tells me:

Error: this.node.layer.getVisibility is not a function

I'm really missed, what can I do?

Best wishes,
