Vaadin14 and @PreserveOnRefresh

Flow
1

Hi,

how will I know when a @PreserveOnRefresh-annotated view gets refreshed?
Is there any listener to attach to the view?

Thanks,
MZ

Hi Marco, I’m afraid such a feature is not supported by Vaadin. However, listening to navigation lifecycle events, e.g. AfterNavigationEvent, might help you. See https://vaadin.com/docs/v14/flow/routing/tutorial-routing-lifecycle.html#afternavigationevent. Whenever the page is refreshed AfterNavigationEvent is fired.

Hi Mehdi, thanks for your reply: I’ll have a look, it might be useful.

Thanks,

I tried this feature but - as I run in a single-view mode, whose content is modified on state changes - the event is not always fired.

So, having a refresh() method to override (like in Vaadin 7-8) would be very useful.

I opened a specific [ticket]
(https://github.com/vaadin/flow/issues/6453).

Thanks,
MZ
