    Default [3.4.0] Ext.Container defaults is not working like described in documentation

    in documentation for container : defaults I can see:

    "If an added item is a config object, and not an instantiated Component, then the default properties are unconditionally applied.
    If the added item is an instantiated Component, then the default properties are applied conditionally so as not to override existing properties in the item.

    but if you try to apply defaults to Components it will allways override them even the compoent has those properties.

    if you run this code will see that all instances created with "new Ext.form.TextField({...})" have all properties with defaults from FormPanel, even first compoenent has values in his config.

    HTML Code:
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>Ext apply defaults to item</title>
        <link rel="stylesheet" type="text/css" href="../../resources/css/ext-all.css"/>
         <script type="text/javascript" src="../../adapter/ext/ext-base.js"></script>
        <script type="text/javascript" src="../../ext-all.js"></script>
        <script type="text/javascript">
            var form = new Ext.form.FormPanel({
                renderTo: Ext.getBody(),
                title: 'Form with defaults: {width: 200}',
                labelWidth: 150,
                defaults: {
                    width: 200,
                    value: 'default value',
                    xProperty: 'default x'
                items: [
                    new Ext.form.TextField({
                        fieldLabel: 'Component width 300',
                        width: 300,
                        value: 'value',
                        xProperty: 'xProperty'
                    new Ext.form.TextField({
                        fieldLabel: 'Component no width'
                        xtype: 'textfield',
                        fieldLabel: 'config width 300',
                        width: 300,
                        value: 'value',se
                        xProperty: 'xProperty'
                        xtype: 'textfield',
                        fieldLabel: 'config no width'
            form.items.each(function(item, i){
                if(console &&{
          , item.width, item.fieldLabel, "xProperty: ", item.xProperty);
        <!-- Common Styles for the examples -->
        <link rel="stylesheet" type="text/css" href="../shared/examples.css"/>
