value for '#{org.jboss.seam.security.identity}' sometimes no

[koenhandekyn]

i'm having some serious "reliability" issues with SEAM 1.2.1 GA on JBOSS 4.0.5. - i have turned off already ' devepment / debug ' configurations.

sometimes the following error is thrown.

SEVERE: Error Rendering View[/tasks.xhtml]
javax.faces.el.EvaluationException: /layout/menu.xhtml @21,120 rendered="#{identity.loggedIn}": Cannot get value for expression '#{org.jboss.seam.security.identity}'

below a first part of the rest of the stack traceat

[gavin.king]

No, thats coming from the JBoss classloader, and tells me you have some packaging / classloading issues.

[colablade]

i'm having the same problem here, and what really puzzles me is that if i press the 'back' button, then repeat the what i did before, no exception is thrown!
most of the time, it just works nicely!

and instead of "org.jboss.seam.security.identity", sometimes i'm also getting "Cannot get value for" "org.jboss.seam.core.actor" and "org.jboss.seam.core.jbpmContext".

so ... any clue?

[colablade]

btw, my class is like

@Name("jbpmWorkingProcessInfoList")
@Scope(ScopeType.APPLICATION)
public class JbpmWorkingProcessInfoList {
 @In
 JbpmContext jbpmContext;

 @In
 private Actor actor;
 ...
}

[colablade]

sorry, i forget to say i'm working on seam 1.2.1 GA and Jboss 4.0.5 GA

[shane.bryzak]

Is this after redeploying a few times? You may need to increase your permgen size.

[koenhandekyn]

in my experience it's not related to an amount of restarts.
i have already increased the perm gen space.
still it happens.

[colablade]

thanks for the reply. but it doesn't look like a 'permgen size' problem for me either. i maintained a list of jbpm process instance in the class as i posted above. and i displayed the list in the web page, with each entry in the list followed by a 'view detail' button. Clicking on the button leads to the display of the information associated to the specific process instance. if i switch between the instances too quickly, it (the exception) happens quite a lot -- at least one out of 8 clicks. if i don't do this 'crazy switching', it doesn't happen frequently -- maybe several times a day.

[james_hays]

Any solutions to this issue?
