Vaadin 14.0.2

Vaadin consists of a set of web components, a Java web framework, configurable themes, tools and a set of app templates.

With every major release, we will change and improve things based on your feedback. This may lead to breaking changes, which will be listed for each part of the platform in the breaking changes section.

Visit vaadin.com to get started.

Support

Vaadin 14 is an LTS (long term support) version, which will be supported for 5 years after the GA (general availability) release. More details of our release model are available on our roadmap page.

Vaadin also provides commercial support and warranty.

New and Noteworthy

Form Layout:

• Update styles after added/removed nodes

Grid:

• Place column-reorder event definition properly
• Make sure the correct scrollTarget is available on attach
• Improvements on related API docs

Text field:

• fix: stuck in invalid state after last validation constraint is removed while invalid
• fix(number-field): step up/down buttons don't work with some values
• Don't adjust decimal places based on step, fix decimal calc

App Layout:

• Update navbar to align items vertically
• refactor: use currentColor for drawer toggle icon
• fix(lumo): improve drawer-toggle appearance (edited)

npm support

Using Bower for frontend dependencies is currently discouraged (by the author), and npm has become the defacto standard. In Vaadin 14 npm is used as the front-end package manager. Bower (compatibility mode) and WebJars are still fully supported in Vaadin 14. Using npm is the recommended mode in Vaadin 14.

Framework

• Support for npm and ES6 modules
• Support for Polymer 3 templates
• Adding @​PreserveOnRefresh on a router layout or route will preserve the user-edited component state when the user refreshes the page by reusing the component instances
• Embedding Flow application is now possible by exporting it as a web component.
• When executing JavaScript from the server-side Java, it is possible to get the return value of the execution to the server-side using Page.executeJs(String expression, Serializable... parameters)
• It is possible to obtain details like screen width & height and time zone on the server-side using Page.retrieveExtendedClientDetails( ExtendedClientDetailsReceiver receiver)
• Simplified styling of application and component with @​CssImport

Components

• Grid rows drag and drop
• Grid columns auto-width
• Customise value representation for Grid Pro
• Menubar component added
• App Layout with drawer
• Clear button visibility APIs
• Dropdown select value change without opening
