[Users] ExtJs Create Radio Button Tree Nodes

[IT Intern]

Dear Andreas,

Thank you for your quick reply.  I tried assigning the overlay container
with a loader group and it is not working for me still :(

function childContainerRadioButtons(text, layerStore, parent, iconCls){

    parent.appendChild(new GeoExt.tree.OverlayLayerContainer({
        text: text,
        layerStore: layerStore,
        expanded: true,
        iconCls: iconCls,  //If not specified, defaults to original image
        loader:{
            baseAttrs:{
                radioGroup: "foo"
            }
        }
    }));

}//end childContainerRadioButtons

I tried group: "foo" also..as for what was I expecting the loader to do with
{param: "LAYERS"}, thats a good question...for some reason I thought I
needed that...

If anyone might know why is still isn't working for me, please drop me a
hint ;)

Thank you for your time,

elshae
