Console.js:35[DEPRECATE][view.Layout#show] Call show() on a component that doesn't ..

[landed]

    launch: function() {

		Ext.widget('mainLayout').show();

I have tried Ext.Viewport.add('mainLayout'); before the line above but I get an error so I am after the correct usage please anyone...

Console.js:35[DEPRECATE][view.Layout#show] Call show() on a component that doesn't currently belong to any container. Please add it to the the Viewport first, i.e: Ext.Viewport.add(component);

[j.k]

Try

var mainView = Ext.widget('mainLayout');
Ext.Viewport.add(mainView);

If I create using items {} fashion will I still need to add and show() the view in the actual class ?
Thanks - at least my main view is showing.

Aaah, Ext.Viewport.add expects an array of components. The following doesn't generate the warning:

var mainView = Ext.widget('mainLayout');
Ext.Viewport.add([mainView]);
