Breaking changes

• Upgrade minimum supported Gradle version to 8.7
  Commit · Pull request

  Jackson 2.18 is incompatible with Gradle 8.4 because it contains classes compiled with Java 22. This change bumps Gradle minumum supported version to 8.7 that supports Java 22.

New features

• Add drag image for DragSource
  Commit · Pull request · Issue · Docs

  Adds DragSource#setDragImage(ComponentDragImage ) and DragSource#setDragImage(Component dragImage, int offsetX, int offsetY). API is used to set image component as a drag image for drag source component. Follows specification of HTML Drag and Drop API for DataTransfer#setDragImage() method.
  Examples:

  CardComponent card = new CardComponent();
  // use Image component as a drag image
  card.setDragImage(new Image("/cards/ace_of_spades.png", "Ace of Spades"));

  // use an arbitrary Flow component as a drag image
  // needs to be present in the DOM
  Span dragImage = new Span("Drag Image Component");
  Style dragImageStyle = dragImage.getElement().getStyle();
  dragImageStyle.setPosition(Style.Position.ABSOLUTE);
  dragImageStyle.setTop("-100px");
  dragImageStyle.setLeft("-100px");
  add(dragImage);
  dragSource.setDragImage(dragImage);

• Extend WebPushMessage with the custom settings
  Commit · Pull request · Issue · Docs

  Adds a Java API for setting the custom options as described in https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorkerRegistration/showNotification#parameters.
  Note that this isn't an experimental feature anymore.

  WebPushAction webPushAction = new WebPushAction("dashboard", "Open Dashboard");
  WebPushOptions webPushOptions = new WebPushOptions(body, List.of(webPushAction), "This is my data", "https://example.com/my-icon.png");
  webPush.sendNotification(subscription, new WebPushMessage(title, webPushOptions));

• Enable easier override for SpringServlet
  Commit · Pull request · Issue · Docs

  Can be done by providing a custom Spring configuration class, see linked docs for more details.

• Add support for customizable projectFileExtensions
  Commit · Pull request · Issue

• Opt-out web components from package.json
  Commit · Pull request · Docs

  Adds new property npm.excludeWebComponents (or npmExcludeWebComponents in Maven configurations). By default, it's false and everything works as before. true will exclude all Vaadin web component dependencies from package.json for development mode (Vite/dev bundle) and production bundle build. Excluded dependencies are all Vaadin core components (e.g. button, grid, login, etc.) and commercial components (e.g. charts, rich-text-editor, etc.), but not lumo/material themes.

All changes

Fixes

• Fix ServletFileUpload header encoding
  Commit · Pull request · Issue

  This change will set ServletFileUpload's header encoding always to UTF-8 in StreamReceiverHandler when request character encoding is null. This ensures that system's default character encoding is not applied when parsing filename of the uploaded file, unless request's character encoding is set otherwise. Only for setups without multipart config for servlet.

• Delay session expiration handling to prevent canceling ongoing navigation
  Commit · Pull request

  Attempts to fix the synchronization issue related to the usage of the Login reported in #12640. The Login component sends the UIDL request for the login event to the server and concurrently submits the form. If processing the form submission performs a session ID change and a request redirect, the UIDL requests might fail with a session expiration response. The Flow client then can cancel the first redirect because it reloads the page due to the session expiration. Lastly, the beacon request hits again a valid session, but a resynchronization is triggered because the previous UIDL request was rejected. This change delays a bit the session expiration handling on Flow client, to allow a potential redirect to complete without being cancelled. However, the client application is immediately set in TERMINATED state.

• Reconnect web components after session expiration (#20407) (CP: 24.5)

• Client side value binding logic (#20431)
  Commit · Pull request · Issue

  Changes client side value binding logic so that if the user modifies the value during server round-trip, the value earlier sent to the server no longer overwrites user's changes once the round-trip finishes. Instead, user's changes are preserved. However, if the server-side value change handling logic actually changes the value and returns the new value to the client, that value will override any user input during round-trip.

Vaadin Flow 24.4.12

All changes

Fixes

• Support serialization of Vaadin scoped beans (#20394)
  Commit · Pull request · Issue

  Makes sure that VaadinSession and UI thread locals are available during both serialization and deserialization, to allow other libraries to perform inspection and injection of Vaadin scoped beans. Also refactors VaadinRouteScope to be independent from VaadinService when fetching RouteScopeOwner annotation for the bean, and replaces VaadinSession.unlock() calls with direct access to the lock instance to prevent unwanted push during bean lookup.

• Resume client to server communication after web socket reconnection (#20283)
  Commit · Pull request · Issue

  When a websocket PUSH connection is closed and re-established because of a network failure, the RequestResponseTracker.hasActiveRequest is not reset, prenvint the Flow client to send additional messages to the server. This change will reset the flag on reconnection. It also will track unsent PUSH message over websocket, to retry the delivery once the connection is re-established, preventing client resynchronization. In addition, it sets a default value of 12 for the Atmospehere maxWebsocketErrorRetries setting, to ensure that the Flow client will attempt to reconnect with web socket transport several times, instead of immediately downgrade to long-polling after first failed connection.

• Reconnect web components after session expiration
  Commit · Pull request · Issue

  After session expiration, Flow client in webcomponent mode send a GET request to the server to re-initialize itself with a valid session cookie. However, the XHR call is done with the withCredentials flag set to false, making the browser ignore the Set-Cookie header in the response. This change forces the withCredential flag to true for resync request so that the new cookie can be handled by the browser and reused in the subsequent request that re-intitializes the embedded component. If PUSH is enabled, it also restores the connection after resynchornization request to make sure pending invocation queue, and especially the webcomponent connected events, can be flushed correctly and sent to the server. Also temporarily suspends hearbeat during resynchronization request to prevent issue with concurrent requests, potentially causing duplicated session expiration handling on the client.
