I have a problem with my first JSF/IceFaces (version 1.8.2) application running on JBoss 5.1.0.
I recieve an exception after a while, telling me about session problems. This is weird, because i do not use sessions in my code at all. The following logs show that none of my backing beans can be instantiated because of this error (from JBoss):

I recognized that the exception is thrown an half hour after the last user activity.
The same problem has been reported on the IceFaces forums:
The proposed solutions were:
This was happening for us once we set the asynchronous mode off
<!-- Specifies to the ICEfaces framework that synchronous update mode is to be used. By default, ICEfaces uses asynchronous update mode to support server-initiated updates (AJAX push). Setting to true will enable synchronous update mode and disable AJAX push features. --> <context-param> <param-name>com.icesoft.faces.synchronousUpdate</param-name> <param-value>true</param-value> </context-param>
When this was false we got the nice little session timed out message. When this was true, session timeout behaviour was stack trace.
and
In the meantime I've switched from ICEfaces 1.8.2 to what's in the svn repository at the moment (1.8.3+). And the behavior has changed. There is no crash anymore.
As to your statement that you aren't using the session anywhere, the stacktrace tells that it is attempting to create a session scoped managed bean when this exception was thrown. So you are definitely using the session :)
Update as per the comments: You should indeed definitely not assign the (request based!!) FacesContext
as a static
variable. Also, injecting of other beans needs to be taken place by <managed-property>
in faces-config.xml
. Otherwise it isn't "injecting" at all, but just manually accessing the other bean. With injecting, you're letting JSF do the work to set the other bean as a property of the current bean. An example can be found here.
