  • Fixes:

    • ⧉ Fix client side validation overriding (#512). PR:548. Ticket:8848

      The workaround for overriding the client side validation for certain components was causing an unnecessary roundtrip to the server side, which also caused two warnings to be logged by Flow each time a disabled or a readonly component was added to the UI. The warning happened twice since two executeJS calls were enqueued: one immediately, and another when attached. Apparently there was no good reason for this behavior. This fix will only apply the executeJS once when the component is attached and it will not require a separate roundtrip to workaround the client side validation overriding the invalid value because the JS execution is enqueued on the "beforeClientResponse" phase when the server side invalid value has been resolved and can be used in the JS execution. Further improvement would be to move the FieldValidationUtil to its own module and reused from there, but that is left for later (?).

Changes since 18.0.3

Reporting Issues

We appreciate if you try to find the most relevant repository to report the issue in. If it is not obvious which project to add issues to, you are always welcome to report any issue at https://github.com/vaadin/platform/issues.

A few rules of thumb will help you and us in finding the correct repository for the issue:

  1. Bug tickets and enhancement requests that are specific to a certain Vaadin component should be posted in the component's Web Component repostory (e.g. https://github.com/vaadin/vaadin-button for Button).
  2. Issues that are not component-specific (e.g. requests for new components) or encompass multiple components should be posted in vaadin-flow-components repository.
  3. If you encounter an issue with Flow which does not seem to be related to a specific component, the problem is likely in Flow itself. The Flow repository is https://github.com/vaadin/flow
  4. If you encounter an issue with Designer, the repository is https://github.com/vaadin/designer
  5. If you encounter an issue with TestBench, the repository is https://github.com/vaadin/testbench
