Public 4.2 Docs Broken
Just another note that all the inline code in the API docs and the examples are currently broken at http://docs.sencha.com/ext-js/4-2/#!/api.
Are you referring to the error message:
Just wanted to make sure there was nothing else.
ReferenceError: Ext is not defined
Thanks for the report! I have opened a bug in our bug tracker.
I see that output in the inline code examples, and I believe running an actual example (from the examples tab) gives a similar error in the browser console.
