What is the replacement for sencha touch 1.1 Ext.dispatch method in sencha touch 2?
I need replacement for code below
listeners:{
    itemtap:function(data,index){
        var record = data.getStore().getAt(index);
         // the record that has been clicked.
         Ext.dispatch({
            controller: 'ControllerName'
            ,action: 'ControllerMethod'
            ,record: record
        });
    }
}
    回答1:
Method Ext.dispatch still exists in Sencha Touch 2: http://docs.sencha.com/touch/2-0/#!/api/Ext.app.Application-method-dispatch
But if you just don't like to use it for some reason, you can get an instance of the controller and call method dicrectly:
Ext.ControllerManager.get('ControllerName').ControllerMethod({record: record});
    回答2:
In sencha touch 2.0 to get the controller instances from anywhere use
<your app name>.app.getController('your controller name');
where your application name is setup in app.js
回答3:
Try this, it should work:
window['AppName'].app.getController('ControllerName').MethodName(Args)
Or, alternatively:
window['AppName'].app.dispatch({
    controller: 'ControllerName',
    action: 'MethodName',
    args:ArgsArray
}
    回答4:
When the call shal be done from a controller, you'll have the application instance by getApplication method, there is a method getControllerInstance which returns an array.
this.getApplication().getControllerInstances()['yourcontrollername'].yourmethod(yourparams)
    回答5:
yourAppName.getApplication().getController('yourControllerId').yourMethodName(args);
