V8, Touchkit5: NavigationButton broken

Flow
1

I’m gradually migrating a large project to Vaadin 8. I’ve included a .jar file of the latest, now end-of-life Touchkit, and have encountered a problem. An IllegalStateException is thrown when a NavigationButton is pressed. There’s none of my code on the stack trace. It appears that the button has a read-only mode set; something that I have not (and could not) do with this type of component.

Any ideas?

Thanks Johannes and Matti. This beta1 version solved it and the IVY dependency is much appreciated.

In case it helps anyone else, I had previously referred to the “Touchkit is dead” blog, which linked to a github repository: https://github.com/vaadin/touchkit. I downloaded from that link and compiled a .jar file. The version there is 5.0-SNAPSHOT, which contained the problem. Perhaps the link on the blog should be re-directed to the touchkit page.
