Can you describe in more detail what you mean by "shared between
sessions"?

That's a really ancient version of Tomahawk...

In modern versions, the place where the data is stored is specified by
the "into" property, as described here:
  http://myfaces.apache.org/tomahawk/tlddoc/t/buffer.html

You aren't specifying an application-scoped variable as the "into"
expression are you?

I can't see any other reason why this would happen. The FacesContext is
a per-request object, and t:buffer (class BufferRenderer) just replaces
the current responseWriter with a newly-created instance to capture the
output. Something would need to be seriously wrong for a request-scoped
variable to leak into another request.

If the "into" expression looks ok, then I suggest you try upgrading. If
you cannot upgrade, then you'll probably need to debug into the
BufferRenderer class.

I haven't heard of anyone having this problem, and have used t:buffer in
the past without having this problem myself (though on a more recent
tomahawk version).

Simon

Hi Simon,

While testing we found that
If a user A is logged from PC A 
and a different user B is logged from PC B with totally different sessions
and different user logins. 
The user B was able to see data from user A in his
browser session, specifically the code between the t:buffer tags in the jsf
page was showing data belonging to a different user.
Both users were logged in around the sametime. It seems like the t:buffer
contents is stored in the FacesContext, and when user B requested his page
the <h:outputText value="<BufferVariable>" />
the <h:outputText? tag picked up the value from the FacesContext for User A.


FYI
Here is the contents of manifest.mf file inside Tomahawk.jar
Implementation-Title: MyFaces
Implementation-Version: 1.1.1 (October 25 2005)
Implementation-Vendor: MyFaces Project Team (http://myfaces.apache.org)



Hope this is helpful.

Thanks
Pravin
