I noticed that the ability to use ListBoxes in data binding was fixed in release 3. We use Uberfire which is at release level 2 of errai. Is there any intention to include that patch into release 2? All UIs have drop down so it is a significant issue that the data binding does not work for these fields - it kind of defeats the whole purpose of using the binding if you have to take a manual approach for all list boxes.
UberFire 0.5.0-SNAPSHOT is now available in the same JBoss Community nexus repo as UberFire 0.4.0-SNAPSHOT. UberFire 0.5.0 is based on Errai 3.0-SNAPSHOT, so you can now take advantage of the new features in Errai 3.
