[Trinidad] SEVERE: Could not find saved view state for token

[Davide Bonicelli <da...@gmail.com>]

Hi all,
   I've developed an application using Hibernate, Spring and Trinidad 1.0.7.
While testing the application during development, everything worked fine.
Now that a higher number of users is using the application concurrently I
can see this error repeated multiple times in my catalina log file:

*SEVERE*: *Could* *not* *find* *saved* *view* *state* *for* *token* XXX

where XXX is the id of the token.

I googled the error and I only found an older post on this forum with no
replies, on which the poster was saying he's getting the same error while
stress testing the trinidad demo application (version 1.2.8) with 30
simulated users.

Does anybody have an idea of what could be the problem that causes this
error? Is it a configuration issue or a bug in Trinidad (or MyFaces)?
My Tomcat session expiration time is set to the standard 30 minutes.

Thanks
Davide
