• Clear CurrentInstance before invoking new session tasks (#6349) (#20255)
  Commit · Pull request · Issue

  Commands enqueued by VaadinSession.access() in general have nothing to do with each other. The only thing they have in common is they share the same VaadinSession (and, by implication, VaadinService). Therefore, if command №1 invoked UI.setCurrent() and command №2 invokes UI.getCurrent(), command №2 should read null, not the random UI from command №1 that it has nothing to do with.

• Allow null response in logout (#20057)
  Commit · Pull request · Issue

  Don't throw NullPointerException in case of null VaadinServletResponse in AuthenticationContext#logout. Tolerate null response better in case when running with @Push(transport = Transport.WEBSOCKET), or when response is null for some other reason. Makes logout also work in WEBSOCKET mode by automatically switching to WEBSOCKET_XHR for one additional request that executes logout.

Vaadin Flow 24.5.0

All Changes since Vaadin Flow 24.4

New features

• Automatic Flow main layouts
  Docs

  Vaadin Flow automatically adds the Flow and Hilla routes to the router layout that is marked with AtLayout new annotation:

  // Main Layout:
  @Layout
  @AnonymousAllowed
   public class MainLayout extends AppLayout {
   }
  
  // Flow route:
  @PermitAll
  @Route("flow") // no layout reference is needed
   public class FlowView extends VerticalLayout {
   }

  Includes the following commits:

  • Automatic Flow layout
    Commit · Pull request

    Automatically match layout for both flow and hilla route. format Add server layout usage information to routes.tsx template This reverts commit bad2fec. Have OutletElement as a tsx file in flow-react jar Add javadoc for auto layout getParentLayout method.

  • Generate layout.json
    Commit · Pull request

    Generate a layout.json for Hilla to automatically enable server layouts part of vaadin/hilla#2709.

• Dynamic menu items in Flow main layout
  Docs

  Collects and provides AtMenu annotated Flow routes and Hilla views filtered by access control resolutions, can be used in the Flow main layout to render links in the navigation bar in a generic way without explicit Java classes for routes:

  // Use dynamic menus in layout class:
  List<MenuEntry> menuEntries = MenuConfiguration.getMenuEntries();
  menuEntries.forEach(entry -> {
     sideNav.addItem(new SideNavItem(entry.title(), entry.path(), new SvgIcon(entry.icon()));
  };
  
  // Flow route
  @Menu(title = "Flow view", icon = "vaadin:group")
  @Route("flow")
   public class FlowView extends VerticalLayout {
   }
  
  // Hilla view
  export const config: ViewConfig = {
     menu: {
       title: "Hilla User page",
       icon: 'vaadin:user'
     }
  };
  export default function Hilla() {
  }

  • Add collectMenuItemsList() to MenuRegistry
    Commit · Pull request · Issue

  • Get menu views api
    Commit · Pull request · Issue

    Create MenuRegistry for getting automatic menu views for population.

  • Filter client routes by authentication and role
    Commit · Pull request

    Add filtering of menu client routes by checking authentication and roles. Do not check for routes in ClientRoutesProvider as the results are generated from the same source data as the data read/generated by MenuRegistry.

• Flow components as children for React-based component
  Doc · Commit · Pull request · Issue

  Allows having Flow Components as children in a ReactAdapterComponent (Flow wrapper for React component).

  // Example of main layout in React with a Flow component as a content in this layout:
  @Layout
  @JsModule("./ReactLayout.tsx")
  @Tag("react-layout")
  public class ReactLayout extends ReactAdapterComponent 
                             implements RouterLayout {
      @Override
      public void showRouterLayoutContent(
                                 HasElement content) {
          if (content != null) {
              // bind Flow component to React element with the "flowContent" key
              getContentElement("flowContent").appendChild(content.getElement());
          }
      }
  }

  // Main Layout in React
  class ReactLayoutElement extends ReactAdapterElement {
     protected render(hooks: RenderHooks) {
     const content = hooks.useContent('flowContent');
      return (
        <div style={{flexGrow: 1, padding: '20px'}}>
          <AppBar position="fixed">
            <Toolbar>
              <Typography variant="h6" component="div">
                React Layout
              </Typography>
            </Toolbar>
          </AppBar>
         {content}
        </div>
      )
    }
  }
  customElements.define('react-layout', ReactLayoutElement);

• HotSwap improvements

  Provides a single endpoint for hotswap tools that internally chooses the best strategy of UI update - full page reload or UI component reload.

  Includes the following commits:

  • API for reloading current route target
    Commit · Pull request

  • Add a common API to integrate with hotswap tools
    Commit · Pull request

• Record support in Binder
  Docs · Commit · Pull request

  Provides an API to use Java Records as bean types for read-only beans in Binder.

• Support for nonce-based strict Content Security Policy
  Docs

  Vaadin Flow isn’t generally compatible with strict CSP rules, however, with some effort, nonce-based strict CSP can be used with Vaadin Flow applications. See the linked documentation for how to set it up.

• Add alternative translate methods to I18NProvider
  Commit · Pull request · Issue

  Adds static I18NProvider#translate methods for alternative way to get translation. Compares to calling getTranslation via VaadinService.getCurrent().getInstantiator().getI18NProvider(). translate methods throws IllegalStateException without active VaadinService.

• Speedup startup time by excluding jars
  Commit · Pull request · Issue

  Optimize class scanning of VaadinServletContextInitializer by excluding some commonly used jars and add support for vaadin.blocked-jar boolean property in META-INF/VAADIN/package.properties to exclude whole jar content from the class scanner.

• Added HasLabelAsText interface to NativeButtonElement.
  Commit · Pull request

• Filterable class scanning of JAR
  Commit · Pull request · Issue

  This change improves optimization of class scanning of VaadinServletContextInitializer by reading optional configuration file within a JAR dependency. Configuration file is a regular properties file that can contain vaadin.allowed-packages or vaadin.blocked-packages to exclude/include packages being scanned by VaadinServletContextInitializer. Package exclusion/inclusion effects only classes in the JAR/module where META-INF/VAADIN/package.properties is located at. Notice that this is only affecting the performance of the class scanning of Vaadin specific annotations and types and this feature is not meant to be used for excluding packages from the whole application. E.g. excluding VaadinServiceInitListener in a Spring application is not stopping Spring and Vaadin initializing it anyway, although some time-consuming actions like DevModeServletContextListener would still exclude it for optimization.

• Add raw html table and related components
  Commit · Pull request

• Create converters for numeric values from NumberField
  Commit · Pull request · Issue

  This pull request introduces converter classes which converts between Numeric data types. This change addresses the need for such converters as outlined in issue #5134. With the availability of a NumberField in Vaadin, it is essential to have converters that facilitate the use of various number formats with this component.

• Add ValueContext.getBinder()
  Commit · Pull request

  original authors: @archiecobbs and @mstahv

• Load Lumo utility CSS by default
  Commit · Pull request

  The imports have been manually defined in all new starter projects for a long time so this is not supposed to break much anything.

• Wrap each enum on a separate line when there are many of them
  Commit · Pull request

• 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

  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.
