Steven Reinisch, now studying at hasso-plattner-institute for software systems engineering, has added some cool refactorings to Xpand and Xtend languages of openArchitectureWare 4.3 during this year's Google Summer Of Code.
During the development he lived in Kiel in order to work in our office at itemis. He managed to understand the code base of Xpand more or less independently. It was a pleasure to work with him and I'm looking forward to future contributions from Steven (He said he's willing to do so :-)).
It's not sure where and how this work will be made available. If we don't put it into oAW 4.3.1, itemis will include it in the distros available at oaw.itemis.eu when it's finished.
Here's a screencast steven made.
