I am a backend dev (RoR/ .Net) who needs to move to front end dev and my team decided that we would use Ext. The question is: Where do we start? While there is a lot of online doc for Ext 2.0 and a few books for 3.0, there is next to nothing for people starting from scratch @ v4.0.
Most tutorials I have found do not work so I can only base my learning on the example provided with the download which (while good) are not the best way to learn when starting from scratch.
So the question is: what would be the best learning path for someone starting fresh (with no knowledge of previous version) with Ext 4.0?
