    Default [4.1B3] Bug with initComponent method of dataview

    [4.1B3] Bug with initComponent method of dataview


    With dataview example taken from documentation, if initComponent method is added to a dataview, TypeError is thrown:

    Code:
    Ext.onReady(function() {
      Ext.define('Image', {
        extend: 'Ext.data.Model',
        fields: [
          { name:'src', type:'string' },
          { name:'caption', type:'string' }
        ]
      });
      
      Ext.create('Ext.data.Store', {
        id:'imagesStore',
        model: 'Image',
        data: [
          { src:'http://www.sencha.com/img/20110215-feat-drawing.png', caption:'Drawing & Charts' },
          { src:'http://www.sencha.com/img/20110215-feat-data.png', caption:'Advanced Data' },
          { src:'http://www.sencha.com/img/20110215-feat-html5.png', caption:'Overhauled Theme' },
          { src:'http://www.sencha.com/img/20110215-feat-perf.png', caption:'Performance Tuned' }
        ]
      });
      
      var imageTpl = new Ext.XTemplate(
          '<tpl for=".">',
            '<div style="margin-bottom: 10px;" class="thumb-wrap">',
              '<img src="{src}" />',
              '<br/><span>{caption}</span>',
            '</div>',
          '</tpl>'
      );
      
      Ext.create('Ext.view.View', {
        store: Ext.data.StoreManager.lookup('imagesStore'),
        tpl: imageTpl,
        itemSelector: 'div.thumb-wrap',
        emptyText: 'No images available',
        renderTo: Ext.getBody(),
        
        // bug: plain initComponent causes throwing a TypeError
        initComponent: function() {
          this.callParent();
        }
      });
    });
    Upon execution above code throws following:
    Code:
    Uncaught TypeError: Cannot call method 'fill' of undefined
      Ext.define.refreshext-all-debug.js:59347
      Base.implement.callParentext-all-debug.js:3609
      Ext.define.refreshext-all-debug.js:100851
      (anonymous function)ext-all-debug.js:59578
      (anonymous function)

    Never use initComponent when instantiating a class, use it when _defining_ a class.
