Problem with build version of app

I migrated the cmd tool from Cmd 250 to Cmd 258.
I did run: sencha app upgrade ../extjs-4.2.0

The app still work perfect.

Then started: sencha app build. The build ended with success with no errors.

But now the has problems. I see this error msg in Chrome:

Uncaught TypeError: Object [object Object] has no method 'isLocalRtl' all-classes.js:1

Does somebody know what the problem here is????

What is isLocalRtl???

Same problem here ...
Sencha Cmd v3.0.2.288.
Upgrade app from ExtJs 4.1.2 to 4.2.0.
The application works perfect but when build the application ​​then ends with the following error :

Code:

---

TypeError: 'undefined' is not a function (evaluating 'this.isLocalRtl()')

---

Hi
I had problem with Ext 4.2.0beta
I moved back to Ext 4.2.0. Problem gone.

I'm also getting this problem. I'm using ExtJs 4.2.0 b285, and Sencha Cmd 3.0.2.

The isLocalRtl method is part of Ext.rtl.AbstractComponent (presumably part of the new Right-to-Left work); the error in question is coming from the definition of Ext.rtl.util.Floating, as packaged up into the all-classes.js file.

So the bug is that, for some reason, Ext.rtl.util.Floating is being packaged up into the all-classes.js file, but the other Ext.rtl classes (especially Ext.rtl.AbstractComponent) are not.

Same Problem here:
ExtJs 4.2.0.265
Cmd 3.0.2.288

Uncaught TypeError: Object [object Object] has no method 'isLocalRtl'

EDIT:
After reading the above post again (thanks!), I added "Ext.rtl.AbstractComponent" to requires in my app.js and the error disappeared. This is an acceptable workaround for the time being.

As a work-around, you can add 'Ext.rtl.*' to the requires section of your application. This ensures that the packaging brings in all of the RTL classes.

I haven't found a way to prevent it needing the RTL classes in the first place.
