Re: Random NullPointerException: "null values not allowed" in JspStateManagerImpl while navigating

[Jeff Bischoff]

Looks like you're trying to serialize something that is null.

Are you sure this isn't coming from your code?

Hi all,

I'm experiencing odd behaviour with myFaces 1.1.3 tomahawk 1.1.2 and facelets 1.1.4 application. Randomly while navigating, NullPointerException occurs.

The stacktrace is quite short:

I've found some trail on the apache mailing list archive but nothing concrete ( discussion trail <http://mail-archives.apache.org/mod_mbox/myfaces-users/200608.mbox/[EMAIL PROTECTED]>) Has anyone seen that? TIA for your good ideas! Harry,
