Components

Changes in vaadin-combo-box-flow

• Fixes:

  • ⧉ Fix setting value to lazy loading ComboBox. PR:478. Ticket:391

    ComboBox should only throw when no items/callback has been set to it. There is a possibility that the value is set but the backend doesn't have this item available, but that is an edge case and something that should not happen and should be possible to prevent by resetting the data and thus a responsibility of the application developer. (cherry picked from commit eb9126910f1f89a40b0a29cfb99da07367b50551)

Changes in vaadin-grid-flow

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
