The wingS development team has released the version 2.1, wich is primarily a bugfix release. Read the announcement on our home page: In parallel, we are working on a AJAX- ified version of wingS. The goal is to make the use of AJAX completely transparent to the developer. During the event dispatching process, components get dirty. The dirty components are collected by the reload manager. When event dispatching has returned, incremental updates for the dirty components are sent to the client. While the AJAX branch is by far not production ready yet, we've already achieved quite promising results. Here's a link to an application, that runs with both, the 2.1 jars and the current build from the AJAX branch: AJAX- ified Version 2.1 Release Version Regards, Holger Engels (wingS Development Team)
