Version: 1.3.0 (using KDE KDE 3.2.1) Installed from: Compiled From Sources OS: Linux Documentation says that "Components can have interfaces (i.e. abstract classes with operations) that allow associations between components". However, a component does not accept an association with an abstract class (with only abstract operations), it requires an interface class. This is somewhat problematic in Java, where some things are better done as abstract classes. For example if the class wants to extend java.util.Observable, this automatically rules out being an interface. Of course one could work around that, but I still feel this is a bug. If this is intentional behaviour, some changes in documentation would be in order.
