Extending from custom view class stalls the sencha build 'create jsb' task

[extjslikeit]

"Ext.define('apam.view.AssignmentNavigation', { extend: 'apam.view.DefaultItemNavigation',
...."
Above fails

but following works (i.e. sencha create jsb.... task completes successfully)
"Ext.define('apam.view.AssignmentNavigation', { extend: 'Ext.navigation.View',
...."

The DefaultItemNavigation is in app.js
"Ext.define('apam.view.DefaultItemNavigation', { extend: 'Ext.navigation.View',
...."


Any clues...

The DefaultItemNavigation is in app.js

Why isn't this in it's own file?

[extjslikeit]

It is in its own file. I mean the view is declared in app.js
..........
views: [ .....
'DefaultItemNavigation',
