You bring up an excellent point; thanks for bringing to our attention that the ext-ux.js target file was not included in the latest RC3 release. We will ensure that it is included in 3.0 final.
JSBuilder2 will be released at the same time Ext 3.0 is. (Tomorrow Monday July 6th) JSBuilder2 is a new Java based tool which provides cross-platform support for building JavaScript and CSS files. It provides a bunch of new enhancements over JSBuilder such as:- Cross-platform
- Easily include targets as dependencies
- Simple JSON based configuration file
- Uses YUI Compressor to improve file minification
- Ability to easily copy resources from development to a deploy package
In terms of file structure changes; the src/ directory replaces the source/ directory. This was done to ensure that a downloaded copy of Ext from SVN was exactly the same as what you got from a deployed project. (Previously this was not the case.)
The pkgs/ directory replaces the build/ directory. We spent several days determining what the most common packages were that people used in conjunction with one another and how they related. This will enable developers to create a much more stream-lined build (smaller and leaner) without too much headache.
We hope that this will help you out for your packaging needs when creating Ext JS apps.
