[B3] VBox-Layout ignores align/pack?

[hl_igig]

I try to use the VBox-Layout. But even the most simple Example doesn't work.

Ext.onReady(function() {
            var panel = Ext.create('Ext.panel.Panel',{
                title:'VBox-Test',
                margin:20,
                width:300,
                height:300,
                layout:'vbox',
                pack:'center',
                align:'center'
                items:[{
                    xtype:'button',
                    text:'Button 1'
                },{
                    xtype:'button',
                    text:'Button 2'
                },{
                    xtype:'button',
                    text:'Button 1'
                }]
            });
            panel.render(document.body);
        }); 

Any hints?

thx

Try:

layout: {
  type: 'vbox', 
  pack:'center', 
  align:'center'
}

should have read the docs more careful
