    Default Unanswered: Error Message: Ext.Msg is undefined

    Unanswered: Error Message: Ext.Msg is undefined


    I am unable to use Ext.Msg inside the controller class. Tried out adding requires : ['Ext.Window.MessageBox'] but still doesn't work. I'm just starting off to use Extjs 4.0. Please let me know what am I missing

    Code:
    Ext.define('Ads.controller.LeftMenu', {
        extend: 'Ext.app.Controller',
    	//requires: ['Ext.Window.MessageBox'],
    	views: ['Viewport'],
        init: function() {
    		console.log('LeftMenu init called');
    		this.control({
            	'menu': {
                	click: this.onLeftMenuClick
            	}
        	});
        },
    	
    	onLeftMenuClick : function( menu, item, eventObj, eOpts ){
    		//Ext.Msg.alert(item.text, item.text);
    		Ext.Msg.alert('Hello', 'Hello');
    		//alert('hello');
    	}
    });

    Code:
    requires: ['Ext.Window.MessageBox']
    should be

    Code:
    requires: ['Ext.window.MessageBox']
    Ext.Window is wrong, Ext.window is correct.

    I don't think you actually need to specifically write the requires: config. I can create messageBoxes without it.

    Is your ComponentQuery for that "menu" item correct? Are u correctly referring to it ? Maybe you're not referring it correctly, that's why when u click it its not alerting anything. (because the control is not registered)

    Try a simple thing first:

    Code:
    onLeftMenuClick : function(){
           alert ("Hahahaha!");
    }
    If u see the alert then your componentquery is correct...

    You do need it as it's not in ext.js. Some other classes may require it that you are using. Ext.Msg won't be created until it Ext.window.MessageBox is dynamically loaded.
