ST Rhino Parse Error with Ext.ux.AccordionList after upgrading Sencha Cmd

I made an app with SA (3.0.4). After upgrading to the last Command version the app cannot be compiled, even though it runs smoothly on the browser.

Trying to compile it for testing the following error is coming up now and again:

Code:

[ERR] C2000: Rhino Parse Error (missing ; before statement =>     "className" : "Ext.ux.AccordionList",) -- /Applications/XAMPP/xamppfiles/htdocs/aprojects/AlvaroDelPortillo/touch/src/ux/AccordionList.js:2:18

... followed by plenty of errors referred to that same file.

Would anyone give me some directions to solve this problem? Thanks in advance.
