Changes

IPageStore rework Unable to render Jira issues macro, execution error.

Storage of pages was reworked:

  • PageStoreManager was broken up into specific managers for storing pages in the request and session and further storage
  • IPageStore and IDataStore were unified

Most application code should be uneffected by this change, IPageManager stays the central mediator between the application and page storage(s).
Users might consider utilizing new features as:

  • CryptingPageStore for encryption of persisted pages
  • FilePageStore with improvements for storing of pages that receive alternating requests

Stores in https://github.com/wicketstuff/core/wiki/DataStores were also updated.

API Changes

Deprecate package org.apache.wicket.util.time from wicket-util Unable to render Jira issues macro, execution error.

Wicket used custom classes from package org.apache.wicket.util.time to handle and manipulate time entities such as "duration" or "current instant".
These classes have been replaced with standard Java 8 classes java.time.Duration and java.time.Instant.

Dependencies

Wicket 9.0 requires Java 11

Upgrade JUnit to version 5  Unable to render Jira issues macro, execution error.

All **Tester classes (e.g. WicketTester, FormTester, TagTester, WebSocketTester) now depend on JUnit 5.x instead of 4.x.

Update CDI integration to CDI 2.0 specification  Unable to render Jira issues macro, execution error.

The old wicket-cdi  module based on CDI 1.0  has been replaced with wicket-cdi-1.1 module (based on CDI 1.1), which has been updated to CDI 2.0. No code change or API break  has been required for this update, hence those who were using wicket-cdi-1.1 should have no problem migrating to the new wicket-cdi  module.

Use JQuery 3.x by default  Unable to render Jira issues macro, execution error.

JQuery 2.x is not maintained anymore by jQuery team. Wicket will use by default latest available 3.x version.


Upgrade Apache Velocity to 2.x  Unable to render Jira issues macro, execution error.

wicket-velocity module now uses org.apache.velocity:velocity-engine-core:2.1 dependency instead of org.apache.velocity:velocity:1.7. Because of this change there are small API changes in the signature of the Wicket Model used for the variables.
