Combobox's view not defined? Trying to set a value. EXTJS 4.0.7

Resuming:

I have an app that displays 3 combos and 1 textbox. The first combo is like "Country", doesnt depend on anything. The second, depends on Country (to show States), and the third depends on the second one.

I have 2 events defined in the store: ancestorValueChange and afterComboRender.

After all combos are defined (and their stores), I search for the combos that DO NOT DEPEND ON ANYONE (like Country), then on these I call store.load() and inside it I call the event afterComboRender, which tries to change the value for a value I have in a variable and that exists in the store records).

So, afterComboRender should change the value (which is in the form '30-2035756720-4', string, and ID and Description are the same.)

When I call afterComboRender and inside it I call combo.setValue('30-2035756720-4'), it reaches a place that says "view is undefined".

I'd like to know if my approach is bad.

Code:

    
onSelectChange: function(record, isSelected, suppressEvent, commitFn) {
        var me = this,
            view = me.view,
            eventName = isSelected ? 'select' : 'deselect';

        if ((suppressEvent || me.fireEvent('before' + eventName, me, record)) !== false &&
                commitFn() !== false ){ //&& Ext.isDefined(view)) {

            if (isSelected) {
                view.onItemSelect(record);  <------ view is not defined.
            } else {
                view.onItemDeselect(record);
            }

            if (!suppressEvent) {
                me.fireEvent(eventName, me, record);
            }
        }
    },
    
    destroy: function(){
        Ext.destroy(this.keyNav);
        this.callParent();
    }
});

My code:

Code:

var idOptionsStore = getStore(idOptionsModel, idOptionsModel, {
  autoLoad: !hasDependency,
comboId: fldId
});
if( hasDependency ) {
  disabled = true;
queryMode = 'remote';
ancestorId = wfId + '-' + prefijo + '-' + dependsOn;

idOptionsStore.addEvents( {'ancestorValueChange':true} );

idOptionsStore.addListener(
    'ancestorValueChange',
function(newValue) {
      var getParamsString = '';
for (var key in newValue.ancestorsValues) {
        if( newValue.ancestorsValues.hasOwnProperty(key) ) {
          var ancestorId = key.substr(key.lastIndexOf('-')+1);
var ancestorValue = newValue.ancestorsValues[key];
var sectoresEnArrayParaURL = '';
getParamsString += "&ancestors["+ancestorId+"]="+ancestorValue;
}
      }
      for(var i=0; i < currentusersector.length; i++) {
          sectoresEnArrayParaURL += '&sectores['+i+']='+currentusersector[i];
}
      getParamsString += sectoresEnArrayParaURL;
index = this.proxy.url.indexOf('&ancestor');
if( index > 0 ) {
        this.proxy.url = this.proxy.url.substr(0, index) + getParamsString;
} else {
        this.proxy.url = this.proxy.url + getParamsString;
}
    },
idOptionsStore
);
}
idOptionsStore.addEvents( {'afterComboRender': true} );
idOptionsStore.addListener(
  'afterComboRender',
function (eOpts) {
    //eOpts = operation.options, bug de ExtJS.
     /** Cargar primer valor en Combos **/
 if (typeof eOpts.combo != 'undefined') {
      var combo = eOpts.combo;
if (typeof combo.autoSelectFirst !== 'undefined' && combo.autoSelectFirst) {
        var primerValor = this.getStore().getAt(0);
if (typeof primerValor !== 'undefined') {
          combo.setValue(primerValor.get('id'));
}
      }
      if (combo.mantenerValor && combo.valorAnterior) {
          combo.setValue(combo.valorAnterior);
}
    }
  });

After the loop that adds all fields / combos


for (var i=0; i < campos.length;i++) {
  if ( campos[i].getXType() == 'combobox' && ! campos[i].hasDependency ) {
    campos[i].getStore().load({
      scope: campos[i],
callback: function()
      {
        this.getStore().fireEvent('afterComboRender', {combo: this});
}
    })
  }
}
