This was something I drew to diagram the original version of X2O in February 2007. I wish I had done it on some type of napkin.

Pretty remarkably, we stuck very much to the plan.

Things we abandoned
We abandoned generating any Cairngorm (or Flex application architecture-specific) code because we couldn't find a part of the framework that would benefit from code generation and not be too constraining at the time.

We also abandoned any "scaffold"-like generation on the Flex side, though, this is still somewhere on the backburner.

For a while prior to releasing, we also generated "view" classes for ActionScript. Basically, these were classes that you could link to MovieClips. Each generated view class would contain a corresponding value object. This was sort of a model-view-controller concept without a controller.

Things we added
We added alot of things that couldn't have been envisioned two years ago...

• Custom methods
  
• Generated JavaScript code so you can build HTML/JS based apps without server-side development
• Encryption of X2O server responses
• Email and file upload support

...and literally hundreds of other minutae along the way.

Hope you enjoyed this look at our past!
