Access to instances from callback

[stoertebeker]

Hi,
I have the following situation within a controller:

//user is an instance of UserLogin (model)
var user = Ext.create(model, this.getLoginform().getValues());


user.save({
  success: function(record) {
             console.log('Login success');
             console.log(record.get('lastname'));
             var mvp = Ext.getCmp('myviewport');
             console.log(mvp);
           },...

What I actually want, is to access an attribute that is part of the view MyViewport. I have also defined a reference to MyViewport (-> myviewport). What i get back from Ext.getCmp() is a pointer to the DOM object and not to the instance of MyViewport.
Outside of the callback I can access the sttribute via this.getMyviewport().attribute.
Maybe i have a fundamental misunderstanding or there is any other mistake.

Any comment or hint is welcome.

you can set the callback scope "where to execute your callback function"

if your user.save is inside a controller method then just pass "this" as scope

user.save({   
       success: function(record)  {                  
           console.log('Login success');              
           console.log(record.get('lastname'));              
           var mvp = Ext.getCmp('myviewport');              console.log(mvp);            
           },...
        scope : this
});

now inside the callback function "this" will point to the controller
