[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-959) NullPointerException in ConversationEntry if stack is null

[Andrew (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBSEAM-959?page=comments#action_12357355 ] 
            
Andrew commented on JBSEAM-959:
-------------------------------

"Don't do redirects from RESTORE_VIEW"

Why not? The JSF specification (at least the JavaDoc) does not mention that this is not allowed, and therefore should be permitted and work without exceptions.

> When the conversation stack is null, the ConversationEntry constructor throws a NullPointerException.
> There is a conditional check earlier in the constructor that causes the conversationIdStack to be set to null.  Then later it checks to see if the stack size is greater than 1.  Kablooey!
> changed to
>  if ( conversationIdStack != null && conversationIdStack.size()>1 )
