[DEPRECATE] warning for LoadMask, Msg, etc. show() method

[estesbubba]

So I am using the default Ext.Viewport to add my cards. Whenever I show any floating components I get this warning:

[DEPRECATE][Ext.MessageBox#show] Showing a component that currently doesn't have any container, please use Ext.Viewport.add() to add this component to the viewport

Now if I do the Ext.Viewport.add() the warning goes away but doing this for every MessageBox, LoadMask, etc. is a pain. Do I really need to add() each one before showing or am I missing something here?

        this.mask = new Ext.LoadMask({
            message: 'Processing...'
        });
        Ext.Viewport.add(this.mask);
        this.mask.show();
