I'm using ExtJs 4.2.0-265, with Sencha Cmd 3.0.2-288.

When I create a build (using 'sencha app build'), the resulting 'all-classes.js' file in the production build folder includes a copy of 'Ext.rtl.util.Floating', but doesn't include any of the other Ext.rtl classes - in particular, it doesn't include Ext.rtl.AbstractComponent.

As a result, the all-classes.js doesn't load, resulting in this error message:

Uncaught TypeError: Object [object Object] has no method 'isLocalRtl'
(The 'isLocalRtl' method is defined on Ext.rtl.AbstractComponent).

Steps to reproduce:

$ sencha -sdk [path to ext-] generate app foo foo
$ cd foo
$ sencha app build
$ open build/foo/production/index.html
