I was just reading this on ExtJS blog and I particulary disliked the part about the designer ....
Constructing your interfaces in code will be a thing of the past. We are releasing a Designer Preview that will allow you to experiment with the designer interface and to explore how configs affect your layout. Soon, you will be able to build your application components using base Ext components and Certified User Extensions.
Code generation is currently not available. Our intentions are to charge a fee for this service and to enable our community to create and sell their creations on our marketplace. Our goals are lofty. We want to be the iTunes of Web App Development.
I really love ExtJS and have been using extensively at work since the version 2.x. I must say I was really disappointed when I read the part about having the designer been available for a "fee". I was waiting for that designer for a long time and seems it would never happen.
ExtJS is pretty well documented but is still not easily accessible to new programmer, I would have loved giving that tool to my boss, for him to make interface so we can design interfaces easily, the whole RAD designer would have give a century of advance to ExtJS on Dojo/JQuery.
I am not really surprised about that move, few month after the whole License crisis .... but I must say the Ext Team really wants to make money and starting to piss me off even if I really like what they are doing.
My last comment would be, I am not sure who gonna sell/buy already made interfaces on an ExtJS component store. ExtJS normally require only few hours to build your own component .... so kind of weird business plan ...
Anyway let's see how the community like to pay to publish interfaces ....
