AFFECTSRootCause

Vaadin Flow only instantiates views when needed — when navigating to a different view. Tension: The setParameter method is invoked, but not the constructor. Outcome: The two callbacks are always called for each navigation into this view in this order.

REQUIRESSolution

Then implement `HasUrlParameter` and friends if you need to. — Finally implement `AfterNavigationObserver`. Tension: The setParameter method is invoked, but not the constructor. Outcome: use the information previously gathered in `setParameter` and/or from the given event to update the UI.
