    Default Unanswered: Why the onMetaChange method isn't called with EXTJS4.0.7 ?

    Unanswered: Why the onMetaChange method isn't called with EXTJS4.0.7 ?


    Hi all,
    at the moment I can create a data Store by AjaxProxy and I can getting the result.
    BUT I saw that the event onMetaChange isn't called as in ExtJs 3...
    Probably it changed the name??? (I hope in this )...
    I think that I need of it because I have a StoreManager management with 'open' dataset (open = dynamic structure) ... so I cannot defining a fixed field object in my model. So, I think to use the metaChange event for update it in runtime.... Is it a correct logic? Do you could help my on this solution... or you know other knew ideas?
    Thank in advance!!!!!

    Thank you,

    Hi Mitchell,

    as told yesterday I'm passed to the beta versione of ExtJS 4.1... It works correctly on Firefox and Chrome but I have some problem with IE 8.

    Only in this browser I saw some execptions:
    Linea: 3619
    Carattere: 13
    Codice: 0
    Messaggio di Errore: Array or arguments object expected
    in ext-4.1.0-beta-2/ext-all-debug.js
    and than:
    Linea: 9
    Carattere: 4003
    Codice: 0
    Messaggio di Errore: Permission denied
    I have semplified the logic, it should shows a very simple chart into a viewport... the same code with extjs 4.0.7 works correctly.

    All starts with a jsp that makes next logic:
    Code:
    ...
    Ext.onReady(function() { 
                    Ext.QuickTips.init();                
                    var chartPanel = Ext.widget('ExtJSChartPanel',config); //by alias                
                    var viewport = new Ext.Viewport(chartPanel);
                });
    ...
    And this is the ExtJSChartPanel.js file:
    Code:
    Ext.define('Sbi.extjs.chart.ExtJSChartPanel', {
        alias: 'widget.ExtJSChartPanel',
        extend: 'Ext.panel.Panel',
        constructor: function(config) {
            var defaultSettings = {
            };
    
            var c = Ext.apply(defaultSettings, config || {});
    
            Ext.apply(this, c);
            
            //this.init();
            this.createExample(c);
            
            this.callParent(this, c);
        }
    
      , createExample: function(config){
           var store = Ext.create('Ext.data.JsonStore', {
                fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
                data: [
                    { 'name': 'metric one',   'data1':10, 'data2':12, 'data3':14, 'data4':8,  'data5':13 },
                    { 'name': 'metric two',   'data1':7,  'data2':8,  'data3':16, 'data4':10, 'data5':3  },
                    { 'name': 'metric three', 'data1':5,  'data2':2,  'data3':14, 'data4':12, 'data5':7  },
                    { 'name': 'metric four',  'data1':2,  'data2':14, 'data3':6,  'data4':1,  'data5':23 },
                    { 'name': 'metric five',  'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33 }
                ]
            });
    
            this.chart = Ext.create('Ext.chart.Chart', {

    HI all,

    too this bug is closed.... the problem was a bad call to the parent constructor method...

    Now it work with the 4.0.1 beta version too.
