This addon is compatible with the official addon as far as it can, but contains breaking changes. If you are experiencing problems like - memory leak caused by UIScoped Beans not released until session destroy - @PreDestroy does not run - ViewScope does not clean up when navigating to same view with different parameters - need a CDI scope for VaadinSession - need to distribute vaadin CDI contexts across a cluster then give it a try. See [readme](https://github.com/wbstr/vaadin-alt-cdi/blob/master/README.md) for details!
