We’re not ready for Vaadin 8 but starting to look into it. We use CDIUI, CDIView, and URI Fragments extensively. One of the big things we see is new History Management to use PushState, which can avoid the use of HashBang. How does that relate to CDIVIew navigation which uses HashBang? Has Navigator’s affect on urls changed with Vaadin 8.
Push state and navigators don’t yet work together. You still need to use #! with Navigator in 8.0 I found this pull request in the repository.
