Qooxdoo 0.6.5 has been released with improvements in the core framework, theming, and server-side (now with Perl).

Check out the showcase for examples, and the release notes for detailed changes.

This released adds an Eclipse license that enables it to be the core of the new Eclipse Rich Ajax Platform (RAP) Project.

What is RAP?

The RAP project aims to enable developers to build rich, AJAX-enabled Web applications by using the Eclipse development model, plug-ins and a Java-only API.

Objectives

• Enable the development of Rich Internet Applications that are based on
  the Eclipse Plugin architecture. The Eclipse OSGi framework (Equinox)
  can run inside of a Web application. This has been demonstrated by several
  parties, and a subproject of the Equinox project has already been
  established (see http://www.eclipse.org/equinox/incubator/server/)
• Enable AJAX UI development based on a Java component library with SWT api. For
  enabling UI development based on a Java component library the project has
  received an initial code contribution from Innoopract (W4Toolkit). NEW: Based on the
  infrastructure provided by this code contributions we have implemented a first
  version of a new widget toolkit with SWT api, called RWT. More info on RWT can be
  found here:
  http://wiki.eclipse.org/index.php/RWTOverview. RWT is using a sophisiticated JavaScript
  framework for client side rendering: qooxdoo.
• Provide a Web Workbench similar to the Eclipse platform workbench:
  • provides selection service (with session scope),
  • provides extension points for action sets, workbench parts,
    perspectives, preference pages, etc.,
  • enables plug-ins to contribute to workbench parts provided by other
    plug-ins (e.g. action contributions)
  • NEW: A first implementation of a web workbench is in CVS
  • Check out the RAP demo: RWT / Workbench demo
  • RWT demo: RWT widget demo
• The RAP API will be aligned with the Eclipse platform API as much as possible

Remember when we every complained at the demand of docs for Prototype?

The image aggroup has newborn docs as a pleasant PDF download for us thanks to Josh Clark.

Are you the kind of person who has always written document.addEventListener("keypress", someFunc, false) and never really looked into the false bit. You just always keep it as false as that is how you copied it from some example the first time?

Hallvord R. M. Steen explains what happens when you go true and capture events:

If you call addEventListener with true as the third argument you create a capturing event. The difference from a normal event is that the capturing listener detects all events in the document before they are sent to the actual target of the event.

Nadav Samet has written a simple article explaining various security attacks called Prepare for Attack!—Making Your Web Applications More Secure.

It explains in simple terms, with simple code examples:

• SQL Injection Attacks
• XSRF: Cross-Site Request Forgery
• XSS: Cross-Site Scripting
