Using Cmd 3.0.0.141, I have successfully generated a workspace and an ext app in that workspace. The application builds correctly until I attempt to integrate the Bryntum Scheduler, where I encounter an error when I try to refresh or build:

"Failed to resolve dependency Sch.panel.SchedulerTree for file ExtCalendar.view.Tree"

My structure is:

workspace
.sencha
build/
common/
ext/
extCalendar/
.sencha/
app.json
index.html
app/
model/
view/
store/
controller/
app.js
sch-all-debug.js (the Bryntum Scheduler file)
I've tried:
Adding a "js" path: ...{"path":"app/sch-all-debug.js"}... to app.json (orginally thought this was all I would have to do)
Adding <script src="app/sch-all-debug.js"> to index.html
Adding Ext.Loader.setConfig({ enabled:true, disableCaching : true }) to app.js
Adding Ext.Loader.setPath('Sch', 'js/Sch') to app.js
Adding Ext.require([ 'Sch.panel.SchedulerTree' ]) to app.js

Seems like I'm missing something rudimentary about the Sch namespace, and I'm not sure how to debug the issue....so, I'm doing a lot of trial and error to no avail.

Any advice?
