    Default initComponent alternative

    Hi there,

    Firstly, if a moderator could please move this topic to it's appropriate forum section - it would be highly appreciated. I'm not exactly sure what topic it would fall under.

    Secondly, my problem: I am creating an accordion, adding children depending on records in a store. I am using the Sencha Designer. I can't override the initComponent (as the designer doesn't let you, as fair as I am aware). Will there be an option to allow one to overwrite/override the initComponent in later versions of the Designer?

    Where exactly should i paste my code?

    I have tried the following events: beforerender, beforeshow, afterrender, render, afterlayout; with the following error:

    Uncaught TypeError: Cannot read property 'dom' of undefined

    var me = Ext.getCmp('siderbarPanel');
    me.sidebar = new Array();
     = Ext.getStore('ModuleFeature');
    Ext.Function.defer(function() { {
            var moduleName = record.raw.ModuleName,
                moduleDescription = record.raw.ModuleDescription,
                featureName = record.raw.FeatureName,
                featureDescription = record.raw.FeatureDescription,
                featureXtype = record.raw.FeatureXtype;
            if(me.hasModule(me,moduleName)) {
                var feature = new Object();
       = featureName;
                feature.description = featureDescription;
                feature.xtype = featureXtype;
            } else {
                var module = new Object();
       = moduleName;
                module.description = moduleDescription;
                module.feature = new Array();
                var feature = new Object();
       = featureName;
                feature.description = featureDescription;
                feature.xtype = featureXtype;
        for (var i = 0; i < me.sidebar.length; i++) {
            var panel = Ext.create('Ext.panel.Panel', {
                title: me.sidebar[i].name        
            for (j = 0; j < me.sidebar[i].feature.length; j++) {     
                    xtype: 'button',
                    text: me.sidebar[i].feature[j].name
    }, 200);
    Help with this would be greatly appreciated. Logging the newly created panels to the console would show what seems to be correctly created children. Only once i try to add them to the panel will the error be thrown.


    PS: On a side note, the Designer isn't exactly colour-blind friendly when it comes to highlighting code

    initComponent(): Create an override class:


    You can override whatever you want in that class.

    UI: Sencha Architect 3.x / ExtJS 4 - 6
    Server side: JEE / EJB 3.x / CDI / JPA 2.x/ JAX-RS / JasperReports
    Application Server: Glassfish / WildFly
    Databases: Oracle / DB2 / MySQL / Firebird
