    Answered: Firing an Event from a store to other components


    Hi team,

    i would like to know that how can i initiate an event from store itself to the other components who wants to listen as data in store changes or loads.
    One possible solution i know is using application level events however i am not able to initiate any application level call from mystore.js file example code given below

    Code:
    Ext.define('NameSpace.store.myStore', {
        extend: 'Ext.data.Store',
    
    
        constructor: function(cfg) {
            var me = this;
            cfg = cfg || {};
            me.callParent([Ext.apply({
                autoLoad: true,
                storeId: 'someID',
                proxy: {
                    type: 'ajax',
                    url: 'http://www.someUrl.com',
                    reader: {
                        type: 'json',
                        root: 'response'                        
                    }
                }
            }, 
            cfg)]);
        },
       load: function()
        {
           this.application.fireEvent('storeisloaded');        
      }
    });
    i can handle events raised by any other component.

    any input or suggestion is appreciated.

  2. Components are not meant to listen to events of other components, that is the job of the controller(s).
    I recommend to read this guide:
    http://docs.sencha.com/ext-js/4-0/#!...n_architecture

    If you really want to, you can fire events on components though (like myPanel.fireEvent('foo')), but this messes up your code.

    Please note that this.control uses ComponentQuery and not everything is a component... Store is not a component. Anything that eventually extends Ext.Component can be used in conjunction with ComponentQuery.
