I see my absence of late here on the forums has been noticed, so I just wanted to give a quick status update.
Since the release of Spring BlazeDS 1.5M1 + Flex Addon, I've been a bit side-tracked (more-so than I originally expected to be) and very heads-down catching up on a backlog of work with my name on it for other Spring projects. In particular, the new resource handling support that showed up in Spring 3.0.4, Comet/WebSocket support (via Atmosphere) for Spring Integration, and a number of other experiments around server-side support of various HTML5 features that showed up in my talk last week at JavaOne. Unfortunately, in order to fully focus on these things, I've had to pull away from the forums. I apologize for any questions that have gone unanswered in that time, but typically the community does a pretty good job of stepping up in my absence. I will definitely spend some time in the next few days catching up on any questions that may have been left hanging.
As for the status of Spring BlazeDS 1.5 and the Flex Roo addon, they will be my sole focus for the remainder of the year now that I've caught up on other tasks, and I hope to be able to reach GA with both sometime in December.
In other good news on this front, some new committers from Adobe have been added to the project, and I've been in the process of reviewing some contributions from them. In particular, they have added the necessary support to ensure that the existing spring-flex core will work with some of the more critical LCDS-only features such as their NIO-based channel endpoints. This code has no direct dependency on LCDS, so we've been able to keep it in the core. In addition, they are working on better integration with Spring for upcoming versions of LCDS.
