New Features in Flow 7.0

Official Gradle Plugin for Vaadin

Due to a build issue, the artifact that the Gradle plugin is based on is broken in 7.0.0 - but 7.0.1 is on the way.
Gradle plugin is now build together with Flow and shipped in Vaadin 20. See documentation for getting started with Gradle.

Other Improvements

• Allow creation of Text and Element from nullable text content
• Add support for parsing query string in QueryParameters
• Implement HasStyle in LitTemplate so you can add class names to the root element

Breaking Changes in 7.0

• ⧉ Move access checker and @AnonymousAllowed to flow-server. PR:10758

• ⧉ Add support for parsing query string in QueryParameters. PR:10521

  A minor API behavior change: Location:getQueryParameters is unified with how HttpServletRequest works: For a query string ?foo&bar a list containing "" is returned for both foo and bar whereas the existing implementation returned empty lists. This is a prerequisite for #10431

• ⧉ Endpoint access is denied by default. PR:10526

• ⧉ Remove theme modules from Flow. PR:10220

  As the theme modules are removed from flow-bom and stop following the flow versioning, this is considered a breaking change. Remove the Lumo and Material theme modules from Flow project to have them in the components project instead. Create a test module with Lumo class used for testing in modules requiring the default theme (Lumo). Closes #10182

• ⧉ Mark AbstractSinglePropertyField class as abstract. PR:9872

• CSS files matching the pattern *.global.css can NOT be imported into a variable in a TypeScript view. This is a limitation related to the global CSS loader feature mentioned below, but this has already been reverted and will not be a limitation in the next pre-release anymore.

Changes in Flow from 7.0.0.rc1

• Fixes:

  • ⧉ Set routes first into the template (#11107). PR:11125.

  • ⧉ Prevent passing bad character to wp (#11099). PR:11113

    The webpack dev-server does not escape " character, as it is not valid URL. This limitation was not checked when passing request to it via DevModeHandlerImpl.

  • ⧉ Don't serve directories as static files (#11072). PR:11103

    Add check to the resource to see if it is a directory and do not serve if this is the case. Fixes #11047

  • ⧉ Avoid NPE in query params parsing (#11075). PR:11094. Ticket:11019

    A colon ":" in the location will not cause a NPE when parsing query parameters

  • ⧉ Annotate default error handlers. (#11063). PR:11090

    Annotate default error handlers with the new annotaton DefaultErrorHandler so that we can also in add-ons have default handlers that can be overridden by user handlers.
