[jira] Commented: (MYFACES-1296) NullpointerException in JspStateManager

    [ http://issues.apache.org/jira/browse/MYFACES-1296?page=comments#action_12377372 ] 

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)

Re: [jira] Commented: (MYFACES-1296) NullpointerException in JspStateManager

Posted by Paul Spencer <pa...@apache.org>.
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.
   http://myfaces.zones.apache.org/dist/maven-repository
