I've started work on a Scala implementation for Ext Direct, so far i got a few examples working in a example project https://github.com/Rovak/ScalextExample. I will be implementing all examples from the documentation, and some extra real-time components using websockets later.
For now it only works with Play Framework 2.1, future versions will be framework independent and will contain unit-tests to ensure stable versions.
I would like to hear from the community which Scala frameworks are popular in combination with Ext JS, and any ideas/suggestions to improve the library.
The project can be found at Github https://github.com/Rovak/Scalext
