[Users] Measure Length and Area UX Tools Give Error

[IT Intern]

Thanks for the response Eric!  Here is the code for my tree as you have
requested :)

layerRoot = new Ext.tree.TreeNode({
                text: "All Layers",
                expanded: true
            });

  layerRoot.appendChild(new GeoExt.tree.BaseLayerContainer({
                text: "Base Layers",
                map: map,
                layerStore: mapPanel.layers,
                expanded: true
            }));

//A few other overlay containers are added similarly...

//Tree menu for layers
            var layerTree = new Ext.tree.TreePanel({
                overflow: 'visible',     // For the Combo popup
                region: "west",
                title: "Map Layers",
                root: layerRoot,
                loader: new Ext.tree.TreeLoader({applyLoader: false}),
                enableDD: true,
                collapsible: true,
                width: 300,
                autoScroll: true,
                expanded: false
            });

//Adding tree to panel
var panel = new Ext.Panel({
                //width: $(window).width(),
                height: $(window).height() - 100,
                //height: 700,
                layout: "border",
                id: 'myViewPort',
                renderTo: document.body,
                items: [layerTree, mapPanel]
                //items: [layerTree, legend, mapPanel]
            });

"Vector layers created by Point, Path and Polygon handlers (used by the
Measure control) have displayInLayerSwitcher set to false, so they
should appear in the tree"

If the displayInLayerSwitcher is set to false, then shouldn't it be that
these layers should* not* show in my tree? :-/

Thank you for your time and assistance,

elshae
