Mario,
The problem sounds similar to a problem I described in earlier post,
titled <h:commandLink target="detailWindow"....> sometimes displays an
exception instead of the expected page (core 1.1.3 from myfaces-repo)
http://mail-archive.com/dev%40myfaces.apache.org/msg13870.html
If it is the same problem, then it exist in the 1.1.3 "release
candidate" posted in the myfaces repo.
I am using the 1.1.3 jars in the myfaces repository.

Mario Ivankovits commented on MYFACES-1296:
-------------------------------------------
This should be fixed in myfaces-core head (per 28.4.2006), could you please
check it.
With the lowered NUMBER_OF_VIEWS_IN_SESSION for sure ;-)
At least it is a fix, though, I dont know if it is the correct one. (SVN revision:
r398003 & r398009)
NullpointerException in JspStateManager
---------------------------------------
Key: MYFACES-1296
URL: http://issues.apache.org/jira/browse/MYFACES-1296
Project: MyFaces Core
Type: Bug
Components: General
Versions: 1.1.2
Environment: JBoss 4.0.1, Tomcat 5
Reporter: Stephan Sichhart
Priority: Critical
Fix For: 1.1.3-SNAPSHOT, 1.1.4-SNAPSHOT
Hi,
I'm having trouble using the 1.1.2 release and latest nightly build. If I do
some massive clicking with the sample application, I get after 30-50 clicks an
NPE within the JspStateManager. In my own app. I get this error after 10 page
request.
This problem only occurs, if I use server state saving. I figured out, that if
I increase the org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION parameter to a
large (500) value, the error does not occur or does not occur yet :-)
I can reproduce this error every time. There is an resolved issue on jira (http://issues.apache.org/jira/browse/MYFACES-1278), which explains exactly my problem. This issue was closed. After discussing the problem with Juergen Melzer, he confirmed that the problem is still there.
regards,
Stephan
