My method -
             layercontainers = [];
             for (i = 0; i < groups.length;i++){
                 layercontainers[i] = {
                     nodeType: "gx_layercontainer",
                     text:groups[i],
                     layerStore: mapPanel.layers,
                     leaf:false,
                     expanded:true,
                     loader:{
                         group: groups[i],
                         filter:function(record){
                             return record.get("layer").group == this.group;
                         }
                     }
                 };
             }
             tree.setRootNode({
                 children: layercontainers
             });

"group" is an attribute that I added to layers. Actually its easier if 
you add group to options as can then set it in layer constructor.
