Ext.Map Zoom trouble

[xiii29]

Hi,
I'm trying to set up a map in some Panel and i've difficulties to set up the default zoom ...

Example :

Ext.define("MyApp.view.Map.MapPanel", {
     extend: 'Ext.Panel',
     xtype: 'mapcard',


     config: {
       iconCls: 'globe1', title: 'Carte',
       items: [
           {
                  xtype:'toolbar',
                  title:'Carte',
                  items: [
                    { xtype:'spacer', },
                    { xtype:'button', text:'Refresh', iconCls:'refresh', iconMask:'true', id:'refreshMapButton' }
                  ], //toolbar items
                  docked: 'top',
           },
           {
                xtype:'map',
                id:'globalmap',
                mapOptions: {
                    zoom:                 10,
                }, // mapOptions
           },
       ],
       layout:'fit',
     }, // config
}); // fin

In the controller, I only center the map :

// Activation de la carte
   onMapRender: function(source, map, eOpts) {
         
         this.getMap().setMapCenter( { latitude: 47.217316595885734, longitude: -1.5465397033691520 } );

         // Another way of Zooming ?
         var map = this.getMap().getMap();
         map.setZoom(10);

var klTronconBF = new google.maps.KmlLayer(
				'http://mykml.kml',
				);
      klTronconBF.setMap(map);


   },

Any ideas ?
