Alpha 21: Renderer API updates

Breaking Changes

• #3003 Renderer API refactor:

  • Now all the renderers (Template, Basic and ComponentRenderers) are part of the flow-data package (moved from flow-server). Existing code needs to update the imported package for the renderers to com.vaadin.flow.data.renderer.*.

  • ComponentTemplateRenderer was renamed to ComponentRenderer. The usage remains the same.

  • The API to set renderers to all components was standardized - setRenderer is now the name of the method to be used in all components (see individual component releases for more details).

Enhancements

• #3505 Allow property being undefined from the server side except interim subrops

Bug Fixes

• #3519 Router.getUrl() now behaves more consistently and fails if lacks parameters

• #3439 Component error messages are treated a bit differently now: hidden instead of being removed

• #3545 flow-maven-plugin treats non-jar files in classpath normally and omits them

• #3540 flow-maven-plugin is able to remove directories outside the project output directory

• #3185 if Router fails to parse a route param, the 404 error is returned now

Alpha20: Component API overhaul in preparation for the beta

This release contains several improvements in preparation for the upcoming beta release.

Breaking Changes

• Related to #3423 :
  • GeneratedPaper* components are no longer provided by the platform. They were used in the past as a way of testing the code generator and to provide features yet not present on Vaadin Components.
  • All GeneratedVaadin* components are now abstract and provide only protected methods. The generated classes are not meant to be used directly - they are just a bridge between the client-side webcomponent and the server implementation. Specific relevant details are listed in each component repository.
  • Most components have had their public API changed or improved due to the changes in the Generated classes. Now only methods meant to be public are actually visible to the end developer.

Enhancements

• Bumped the version of all webjars used by Flow, to match the beta releases of the Vaadin elements #3516
• @AllowClientUpdates now can be used without parameters, which implies ClientUpdateMode.ALLOW #3497

Bug Fixes

• Javadocs errors and warnings that prevented the javadoc package deployment to Maven repositories are now fixed #3508
• Model properties on the client-side that are not updatable on the server-side are not transmitted anymore #3425
