Hi All,

I'm new to ExtJS.
In my application I do have 3 views. I'm changing the Views to a Viewport
using the following lines of code.

Ext.getCmp('myViewport').removeAll();
Ext.getCmp('myViewport').add(Ext.create('MyProject.view.Dashboard'));
Ext.getCmp('myViewport').doLayout();


Is this the actual way of displaying view to a Viewport?
Also I'm confused if the last line of code[Ext.getCmp('myViewport').doLayout();] is actually required?

Please help.
