Known Issues and Limitations
This is the prerelease version of Vaadin 22 for evaluating a number of new features and bug fixes. The API in this prerelease version is not considered final and may change based on user feedback.
Flow
- The Template-in-Template feature has some limitations
- Links matching the context do not result in browser page load by default, instead they are handled with application routing. To opt-out, set the
router-ignoreattribute on the anchor element. This opt-out is needed for cases when native browser navigation is necessary, e. g., when usingAnchorto link aStreamResourcedownload.
Migrating from Vaadin 8
Migrating from Vaadin 10-14
Migrating from Vaadin 21
Update the Vaadin version in the build files, and check if the project is using any of the breaking changes mentioned in the 'New and Noteworthy' section above.
In addition, in the case of using the now deprecated PolymerTemplate in views, we encourage to migrate to LitTemplate.
