Learning path for Ext 4?
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?

I suggest doing the first steps with Ext3, best is to get a book as "ExtJS in Action"
Ext4 comes with a compatiblity layer which let you run all Ext3 examples with Ext4 (probably)
A good way is to follow the 4-forums to get an idea what you need to be prepared.
In the 4-docs there are some basic tips, but they will be completed.
It's not that hard as you might think, you have to start understanding what a container is and how to fill containers with items.vg Steffen

For truth is hard. When i started using 0.33 I release application using 1.0
When release 1.xx they release 2.00 New branch Code
When release application 3.XXX .They release branch 4 code..
And the mostly problemm.... fast changing structure..
** I'm working new code branch 3 .No choice for current now.. Performance still okay eventhough using iframe...

The reality is:
Learning ExtJS is hard because is a huge, complex and complete library.
But worth the effort.
Even if there is a lot of hipe about ExtJS 4 you should first learn 3 series with the aid of "ExtJS in action". The book is well written and, as all "in action", takes you from simpler things like "Hello world" to a complex data manipulation. The book cost about $30 in PDF so is not a big investment.
The only thing I feel that has very little support or "how to" is the server side: I think sencha should invest on writting some kind of base code in main server side languages (Java, net, php) to aid new commers to get up and running quickly.

If you learn ExtJS 3 (because of the books out there) the feel of ExtJS 4 will be very familiar. There are some differences but the feel is much the same.Mitchell Simoens @SenchaMitch

Thanks guys. I am already very familiar with dynamic language, being a Rubyist. While I have to do some catch up with js, this is not my main issue. Same for the server side code, Ruby on Rails (or .Net) can send and consume JSON objects very easily.
I got the EXT in action book. Started to read it, I just feel bad learning stuff that wont be valid for Ext 4...
I am very intrigued by the new MVC stuff in v4 since it relates very closely to what I am already doing with Rails/ ASP MVC. Too bad the documentation is not finished yet.
Also, any good blogs I should follow? The rails community is filled with good blogs but I have had a hard time to find more than a few for Ext and none seemed to talk about MVC. I may have to start one...
