${cocoon.continuation.parent.parent.id}??

[Stephan Coboos]

Hello,

I wan't to implement a undo feature so I'am calling 
${cocoon.continuation.parent.parent.id} in a JXTemplate to get the 
continuation created before this continuation but it doesn't work. 
${cocoon.continuation.parent.parent.id} returns only a empty string, 
everytime, but why? "cocoon.continuation.parent" should return a 
WebContinuation and the second call "parent" should return the 
WebContinuation of the continuation, right? What's wrong here?

Thank you!

Regards Stephan
