Only an idea, but without warranty. 
Could you please try to add the layers to the map before creating the ScaleSelectorCombo (with map.addLayers()) ?

Hi all,

I have an issue
with the ScaleSelectorCombo developed by Cedric Moullet (http://dev.geoext.org/sandbox/cmoullet/ux/ScaleSelectorCombo/examples/ScaleSelectorComboExample.html).



In my
interface, the Combobox allowing to switch scales stucks at “1 : undefined” (see in the attached).

I don’t
know where this issue comes from.

I specify
that when I run the ScaleSelectorComboExample.html in my own server it works.

Also, the zoom-chooser
example works (http://dev.geoext.org/trunk/geoext/examples/zoom-chooser.html).

 

Thanks
for any help.

Here is my code:

 

var map; 

 

Ext.onReady(function()
{

 

var
options, layer;

            

options = {

            maxExtent: new OpenLayers.Bounds(0,
1300000, 1500000, 3000000),

            maxResolution: 'auto',

            controls: [new
OpenLayers.Control.KeyboardDefaults(),new
OpenLayers.Control.MousePosition({"numDigits": 2}),new
OpenLayers.Control.Navigation(), new OpenLayers.Control.Scale()],

            scales: [12500, 25000, 50000,
100000, 200000, 500000,1500000],

                                   units: 'm',

            projection: new
OpenLayers.Projection("EPSG:27572"),

        };

 

 

map = new
OpenLayers.Map(options);

 

 

var
scaleSelectorCombo = new GeoExt.ux.form.ScaleSelectorCombo({

        map: map,

        fakeScaleValue: ["12500",
"25000", "50000", "100000", "200000",
"500000","1500000"]

                        });

 

var
viewport = new Ext.Viewport({

                                               layout:
'border',

                                               items:
[{

                                                                       region:'center',

                                                                       id:

‘Title’,

                                                                       xtype: 'gx_mappanel',

                                                                       map:
map,

                                                                       split:

[wms18,wms7,wms5],



                                                                       contentEl:
'center',        



                                                                       bbar:
[scaleSelectorCombo] 

                                                              }]

                                   });
