I cannot tell you, or express the deep frustration and anger I feel when a company who is so public, and who create such good software produces a tool to fulfill a desired task, but the documentation is near non-existent, the support lacking, and the tool itself, a piece of “junk” from the pits of hell. <rant over Sencha>
Moving along, if you want to build custom ExtJs, cause obviously the default one is too big to be used on production websites; here is the process to go about:
- Read This with a focus on the new MVC model as well as Sencha SDK –http://www.sencha.com/learn/getting-started-with-ext-js-4/
- Download the SDK (version 2 and not 1.2.3)
- Huge thanks to Sottilde – http://www.sencha.com/forum/showthread.php?203663-Sencha-SDK-Tools-2.0-and-ExtJS4-The-Missing-Docs (this is a must) – make sure you download the new PhantomJS file
- On the latter part of that forum, I posted my index-build.html, my configuration file (Layout.js) and some tips as well (especially if you using ASP.NET)
Hope that helps ya!
