Hi Gero, As I introduced in the "Hello Email", I'm going to participate in GSoC 2009 with the "Web-based BPEL debugger for Apache ODE" project. So, I have something to say about your suggestion.
First, I tried Oryx and found it's a excellent environment for BPEL modeling as well as debugging. I think that's a great idea to integrate Oryx and Apache ODE. In fact, I myself did intent to use Extjs to implement the frontend for BPEL debugger as ExtJS is being a most robust DHTML-based RIAs platform. I experimented a lot with ExtJS in some rich internet applications. Personally, I think that ExtJS provided me almost things I need to make hight interactive applications with good performance (in my case it's an Web-based Restaurant management application). Therefore, I'll do some study in your two components soon. Hope that you all could give me some advices in my coming proposal !
