This is a known issue with gwt, see the issue tracker for details. However, don't forget that this gives the GWT dev team the possibility to change the internal behavior of classes as they don't have to worry about breaking changes because they are extended... So it makes it easier for the dev team to "move on" adding/changing features. On the other hand, copying a class and adding your own stuff isn't that much work ;)
But still, I have to admit, that things could be set up a bit more OO such that improves extendibility. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
