Question

When I’m trying to open new Panel after button tap I always get this error:

Uncaught Error: [ERROR][Ext.Container#factoryItem] Invalid config, must be a valid config object

Here is the function (Located in custom controller):

push : function(navigationView, viewClass) {
    navigationView.push(viewClass);
}

And this is how it’s called (Located in controller class that extends custom controller):

push(this.getNvw_main(), 'First.view.HomePage');

Thanks for help in advance.

Well, view must be instatiated in order to pushed:

push : function(navigationView, viewClass) {
    var view = Ext.ClassManager.instantiate(viewClass);
    navigationView.push(view);
}
