Manfred Hantschel commented on TAPESTRY-1833:
---------------------------------------------

I cant get access to the session data. Usually the session cookie is 
automatically sent along with the xhr. But our application has cookies turned 
off, which means that the url has to contain the jsessionid. The jsessionid is 
added to the url by calling the ServletResponse.encodeURL method. But this 
method is not called, because the last parameter in the constructLink method is 
set to false.

As a result: cookies turned on, i have access to the session data. cookies 
turned off, i dont have access to the session data. this even occures if the 
webapp has cookies turn on, but the browser does not support cookies.

i have tested the above patch, and it works well.

> The URLs created by XTile do not contain the jsession-id when used with 
> cookies turned off. This is because the link is created with "stateful" set 
> to false (see XTileService.java, line 76). Turning this to true fixes the 
> problem and the URLs are generated including the jsession-id.
