History Management (refresh button)

Question

Please give me an idea of ​​data management in GWT. I use Gwt in the project of my travel portal, and my web pages are linked to the previous page data, but when I click the browser refresh button, then my data is lost. so please tell me if there is a way to handle this problem.

Answer 1

The GWT history class cannot be used to control page refresh (backward / forward only).

Click the update button, send a request to the server, and the application status will be restarted from the server. All this. You have to deal with this.
