Apache Click 2.0.1 now available

Apache Click 2.0.1 is the first release from the Apache Software Foundation Incubator and is based on the 1.5.1 code base.

Both 1.5.1 and 2.0.1 are considered stable and only bug fixes will be applied to these branches. New development will happen on 2.1.0, the next major version of Apache Click.

For this release we had to make some changes especially around incompatible licensed third-party software. Below is a short summary of these changes. More details and upgrade notes can be found in Roadmap and Changes.

Changes are:
  • Packages were renamed to ''. When upgrading from older releases you will need to convert from '' to ''.
  • DateField used the incompatibly licensed JSCalendar which had to be dropped. Don't worry though, DateField still exists and has been converted to a TextField which understands how to parse and format Date objects. Further a new Click Calendar project was created which is a port of the old DateField functionality. The Click Calendar jar contains a single class called CalendarField which subclasses DateField and has the same API and functionality as the old DateField. When upgrading you can just rename your old DateField to CalendarField to get the popup calendar working.
  • The Chart controls was also using an incompatible licensed JavaScript library and these components was removed. A new project called Click Charts was created for these components. They still use the '' package so no code changes will be necessary.
The next major release will be 2.1.0 and a new feature roadmap is being determined.

Apache Click is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
