The new version “1.2.0” of mvvmFX was released.

We have received lots of feedback for the new beta features of our last release, especially for the ModelWrapper and the Commands. Therefore this release mainly contains improvements for these two features.

Commands

• The Command interface now has a progress property similar to the progress property of JavaFX’s Task class. The DelegateCommand is now implemented as a subclass of Service. Instead of a ‘Runnable’ it now takes a ‘Supplier' as argument where `Action` is a subclass of `Task`.

• The ‘Command’ has now a property ‘notExecutable’ which is the negated version of ‘executable’. This way binding to the ‘disable’ property of a Button is easier.

ModelWrapper

• In version 1.1.0 the ModelWrapper was creating fields of type Property<String>, Property<Integer>, Property<Number> and so on. This makes databinding complicated. In the new release the type ìs StringProperty and IntegerProperty etc. which will simplify data binding a lot.

Notifications

• It is now possible to send notifications directly from the ViewModel to the corresponding View without using the global NotificationCenter.

• A bug was fixed where an observer was still registered after unsubscribe when the same observer instance was subscribed multiple times.
