Sencha cmd 5 minify issue

Question

I am trying to minify sencha 5 project with sencha cmd, but it always failed.

sencha generate app -ext demoApp ./demoApp

Then I try to minify the app, by typing

sencha app build production

For blank project, the minify success, I can run in my local web server. Then I change the existing project that have been created, just add one button to display popup window (and the information displayed by xtype "displayfield").

Before it minified & after add one button to display popup, it works normal (tested in browser, click the button, the popup and information showed correctly). After minified, it doesn't work,

GET http://localhost/test/sencha/demoApp/widget/displayfield.js?_dc=1429726459576 404 not found.

"NetworkError: 404 Not Found - http://localhost/test/sencha/demoApp/widget/displayfield.js?_dc=1429726459576 "

Is it weird? If I change the xtype "displayfield" to "textfield" it works normal, or if I change to "button" and change fieldLabel to text, it works!

Anyone have succesfull minify sencha 5 with sencha cmd? My Sencha Cmd version is 5.1.2.52 and I use sencha 5.1.0.107.

I attach the original app folder code original in here and my changes app code in here

Many thanks!

Add into requires 'Ext.form.field.Display'

requires: [
   'demoApp.view.window.WindowViewController',
   'Ext.form.field.Display'
],
