    Default App build with Google Maps

    Hi,
    I have an app that use Google map.
    When I run command sencha app build testing
    or production I have this error :
    [ERROR] ReferenceError: Can't find variable: google
    Stack trace: http://localhost:8087/app/view/Carto.js?_dc=1344325889171 : 1 : Anonymous

    File in question :
    Code:
    Ext.define('PBGeo.view.Carto', {
      extend : 'Ext.Panel',
      xtype : 'carto',
      requires : [ 'Ext.Map','Ext.SegmentedButton'],
      config : {
        layout : 'fit',   
        items : [ {
          xtype : 'toolbar',
          docked : 'top',
          scrollable:true,
          items : [ {
            xtype: 'segmentedbutton',
            allowMultiple: true,
            defaults: {
              iconMask: true
            },
            items:[{iconCls : 'cinema', id:'cinema'},
                   {iconCls : 'resto', id:'resto'},
                   {iconCls : 'favorites', id:'favoris'}]
          } ]
        }, {
          xtype : 'map',
          flex: 1,
          id: 'carte',
          useCurrentLocation : false,
          mapOptions : {
            center : new google.maps.LatLng(47.214292,-1.556175),
            streetViewControl : false,
            panControl : false,
            zoom : 15,
            zoomControl : true,
            zoomControlOptions : {
              position : google.maps.ControlPosition.LEFT_CENTER
            }
          }
        } ]
      }
    });
    Script tag for API Map is in index.html.
    How to resolve this ?

    This happens when your app files aren't downloaded and executed after the google maps JS file is downloaded and executed. This is because you are trying to create an instance as a property. Example:

    Code:
          mapOptions : {
            center : new google.maps.LatLng(47.214292,-1.556175)

    Or use the applyMapOptions method in your own map subclass.

    Finally I have not succeeded to use applyMapOptions in a subclass so I choose to define map options in maprender events.

    Thanks for your help.
