[Users] LayerNodeUI and ZoomSlider

[Hugo]

Hello all,

At the moment i'm facing two problems in my app. The first is related with
baselayers from google in a tree with the RadioButton plugin. The thing is:
if i define the baselayer node not to be expanded the layer is correctly
displayed, however when i expand the base layer node i get a blank map and
only after selecting a new baselayer things get drawn again. If instead i
define the baselayer node to be expanded the layers are all shifted to the
upper left corn of the mappanel but no blank map is being displayed as in
the first option. I've just used the example tree.html to implement the
treepanel.

Is this a known problem or is there any other way to accomplish this? If i
use a normal tree panel without the radiobutton plugin everything works
fine... but obsviously i'm willing to get the radio button there. Any
suggestions?

My second problem, i have alreadey posted some days ago but got no feedback.
I have a sacle combobox and a zoomslider control. When the app is loaded the
scale shown in the combobox is different then the one on the zoomslider
(1:6933504 vs 1:108336). If i drag it to increase zoom, nothing happens at
the first time but from there it starts to make the zooms and the scale
values are the same between the zoomslider and the scale combobox. However,
i'm not able to zoom to the fullextent with the zoomslider anymore. I think
this is related with my definitions on the zoom levels of google base
layers. Here is my code:

var gstreets = new OpenLayers.Layer.Google(
                "Google Streets",
                {MIN_ZOOM_LEVEL: 6, MAX_ZOOM_LEVEL: 20, 'type':
G_NORMAL_MAP, 'sphericalMercator': true}
 );
 var gsat = new OpenLayers.Layer.Google(
                "Google Satellite",
                {MIN_ZOOM_LEVEL: 6, MAX_ZOOM_LEVEL: 20, 'type':
G_SATELLITE_MAP, 'sphericalMercator': true}
 );


var mapPanel = new GeoExt.MapPanel({
                region: 'center',
                id: 'mappanel',
                height: 377,
                width: 500,
                map: map,
                tbar: [toolbar, zoomSelector],
                border: true,
                items: [{
                    xtype: "gx_zoomslider",
                    vertical: true,
                    height: 100,
                    x: 10,
                    y: 20,
                    plugins: new GeoExt.ZoomSliderTip({
                        template: "<div> Escala: 1:{scale}</div><div>
Resolução: {resolution}</div><div> ZOOM: {zoom}</div>"
                    })
                }]
});

The scale combobox code is the same as the online example.

Both these problems are not throwing any errors into the firebug console.
Any help is more than appreciated ;)
Thanks in advance,

Hugo
