    Default child = new Ext.Panel({ renderTo: parent.body.id }) vs parent.add(child)

    child = new Ext.Panel({ renderTo: parent.body.id }) vs parent.add(child)


    Is there a required sequence of events that determines which way you must add a child panel to a parent panel (container)? The documentation states that there is a Panel.add() method, but in the case below it doesn't seem to render the card layout widget. I can make the below code work by adding a renderTo: body.body.id attribute to the card's initialization parameters, but things must be different when I'm adding the child to a TabPanel parent.

    Code:
    body = new Ext.Panel({region: 'center', id: 'center', margins: '5 5 5 5', bodyStyle: 'padding: 5px;'})
    view = new Ext.Viewport({id: 'viewport', layout: 'border', items: [body]})
    card = new Ext.Panel({
      id: 'cardLayout',
      title: 'Card Layout',
      layout: 'card',
      activeItem: 0,
      items: [
        {
          id: 'card1',
          html: '<div>Card 1</div>'
        },{
          id: 'card2',
          html: '<div>Card 2</div>'
        }
      ]
    });
    body.add(card);

    you have to call doLayout() when you "add"
    body.add(...);
    body.doLayout();

    Ummm... that was so easy, I'm embarrassed.

    This seems to make sense so that multiple children could be added to the parent object without incurring multiple layout redraws.
