[Users] Change Image Icon for layers nodes in TreePanel GeoExt 1.1

[dustin.r.blankenship at accenturefederal.com]

This is how we've done it:

var layerTreeStore = Ext.create('Ext.data.TreeStore', {
            model: 'GeoExt.data.LayerTreeModel',
            root: {
                expanded: true,
                plugins: [{
                    ptype: 'gx_layercontainer',
                    loader: {
                        baseAttrs: {
                            iconCls: 'eventNodeIcon'
                        },
                        store: layerStore
                    }
                }]
            }
        });

Where the "eventNodeIcon" is a css class that uses a background image. For us it's just blank.

Hi everyone, I am trying to change the image icon of a layer node in a
TreePanel but always shows me the default one of the class
".x-tree-node-leaf .x-tree-node-icon". Searching for Internet  in some
pages the createNode function is mention in a loader, but I am trying it
and it doesn´t works. Some help is appreciated. Here is my code:


var treeConfig = [ {
                nodeType : "gx_baselayercontainer",
                text : "Ortofotos"
            }, {
                nodeType : "gx_overlaylayercontainer",
                text : "Capas Vectoriales",
                expanded : true,
                // render the nodes inside this container with a radio
button,
                // and assign them the group "foo".
                loader : {
                    baseAttrs : {
                        radioGroup : "foo",
                        uiProvider : "layernodeui",
                    },
                      createNode: function(attr) {
                       attr.iconCls = "nuevaClase";
                       return
 GeoExt.tree.LayerParamLoader.prototype.createNode.apply(this, attr);
                    }
                }
            } ];

Thanks!!!
