Sencha touch picker Error: Cannot read property 'dom' of null

Question

I have created one picker in sencha touch.

Then added into viewport like this:

Ext.Viewport.add(picker);
picker.show();

Then when I try to remove it from viewport it is throwing js error in console. code is:

Ext.Viewport.remove(picker, true);

Cannot read property 'dom' of null in Container.js

Ext.Viewport.remove(picker, true);

You need to put above code in defer as below. It requires at least more delay.

Ext.defer(function(){
      Ext.Viewport.remove(picker, false);
}, 500);

thanks but I require 500ms time for defer. 'cause after destroying the picker code try to execute some code in Container.js hence we required to destroy picker after execution of all code. – Dr. Piyush Dholariya Dec 28 '15 at 07:19
