i saw what chris did, and indeed, it’s the most powerful js framework i have seen.

i still maintain though that there needs to be a wrapper (for Rails, a helper) so that you can generate the appropriate js code, with no opportunities for errors.

It’s very hackable, with good documentation and was created by Jack Slocum, who should be considered one of the top javascript gurus out there. I use it with a php backend, and would recommend it for almost any js intensive project.

In fact, I spent a few months creating my own vendor/plugin wrapper for Ext components but I’ve recently walked away from it. there’s still a place for a ruby classes generating Ext. I’ll figure it out.

You are aware it’s a software-only robot right?
