Dear Sencha!

I tried Sencha Touch 2.0 some time ago and now, when I'm back to ExtJS, I've tried attribute xclass in configs and it doesn't work. Is there any alternative for xclass in ExtJS 4.1?

I think Sencha Touch and ExtJS should be consistent in class system implementation. Is there anything I missed? Thank you for explanation.

Best regards!
