Spring webflow and Code completion

I'm not sure if I fail to see how to use the "Code completion also recognizes MVC model attributes" and var elements that are declared in the flow.xml file. Using EAP 9.0.4 build IU-95.538 and are not sure if this isn't implemented or if I'm doing something wrong. I guess it falls into stuff like http://devnet.jetbrains.net/thread/279020, only thing is that I'm still using Spring 2.5.6...



... to add more info:

I create a var with a name and a class. And the var is used as the view-state's model, but I can't see it using code completion in the jsp.
