Enhancements
New ZK Less Engine
- Available for ZK:
-
The zkless-engine-maven-plugin has been replaced by the zkless-engine npm module (github). It provides a command line interface (CLI) to significantly reduce the general theme build times and the development turn-around when customizing ZK themes (via incremental watch compiler and live reloading in the browser).
This CLI can invoked directly as and integrated into maven or gradle build, making the former - more limited and slower - maven plugin obsolete.
More details in the README
When upgrading a theme to ZK 9 you'll have to escape ZK specific syntax using the escape (e) function. (here the commit upgrading ZK's default styles)
Upgrade jQuery version
- Available for ZK:
-
The underlying jQuery version is upgraded to 1.12.4 to include security fixes.
Upgrade Notes
Upgrade Tips
- The Java binary-compatible level is Java 8 since ZK 9.
- ZK Databinding 1 is moved to a legacy module "zkplus-legacy".
- ZK DSP Library is moved to a new module "zweb-dsp".
- SimpleLocalTimeConstraint is used by default instead of SimpleConstraint in Timebox and Timepicker.
- It is advised to use Notification.show instead of Clients.showNotification, as the former follows single responsibility principle.
