Vaadin table not updating
The servlet receives HTTP requests from the client and interprets them as events of the specific user session.
Events are associated with components of the user interface and delivered to event listeners defined in the application.
So, for example, if you registered a property change listener like this: double amount; JFormatted Text Field amount Field; ...
amount Property Change Listener("value", new Formatted Text Field Listener()); ...
Server-side approach allows you to develop user interface for your web application in almost the same way as the interface of traditional Java applications with direct access to data and services on the server.
But what if the entire client-server application was developed using Java?
Why not to make the client part “native” to the browser in compliance with the most modern usability concepts?
You can register a property change listener in two ways.
The first uses the method Keyboard Focus Manager focus Manager = Keyboard Focus Current Keyboard Focus Manager(); focus Property Change Listener(new Focus Manager Listener()); ...Server part of the application is executed as a traditional Vaadin servlet of the Java application server.
