I'm using Eclipse and was experimenting with WebDriver, DBunit, Maven and the likes. One fine moment I needed to add a Reference Library (right click project > Properties > Java Build Path), and I'm suddenly getting the error "The currently displayed page contains invalid values." :(
Any ideas? I've already re-installed Eclipse and re-instated my workspace but the problem occurred again.
I had the same issue. Installing the updates in Eclipse Mars fixed the issue for me.
