Best Approach to retrieve a session ID in Tapestry 5.1

[Mark Heimann <mh...@steroid-interactive.com>]

Hi everyone,

I was wondering what would be the best approach to retrieve a session ID using Tapestry 5.1. My understanding is that the wrappers Tapestry creates around the HttpSession object does not expose a getId() method that would return a string representation of the session to me.

I have tried injecting the HttpServletRequest into my page class and retrieving the un-wrapped version of the session object from there in order to be able to call said getId() method. Is Tapestry going to notice that I mess around with the un-wrapped request and session objects or would you expect it to break at some point?

The reason why I need to access the session ID is that I need to supply it as a parameter to a Flash object on the page and as far as I know you can't rely on session cookies when it comes to Flash making HTTP calls.

Thanks a lot in advance!

Cheers,
Mark

I think your approach is ok. The reason for the wrapper objects are (I think) to provide some additional functionality such as "Session#isInvalidated" and some clustering optimizations. 
If you call Session#invalidate the session object remembers it so that you can ask isInvalidated later, but that seems to be the only thing the wrapper keeps track of.

Hope that was helpful :)
