Simon, This does also make no sense to me and therefore I asked this question ;-) I did not see this problem in any project so far and all of my beans are working fine and living as expected.
The bean has session scope and the 2 instances are created in the same session. I don't use a custom VariableResolver and the bean is defined once. The onresize event is fired a few times in a very short time, maybe that is causing the problem... I try to debug this further next week and if I have some free time I'll create a small sample app with an ajax link and a normal link.

When an EL expression referencing this bean is evaluated and the bean is found not to exist in any scope then the object is created and a reference to it is placed into the http session. After that, any EL expression which references that object will retrieve it from the session. This all works fine for me, and for everybody else in the world AFAIK. I'm pretty sure that what you *think* is happening is *not* what is actually occurring. The options I see are: * the bean is being created in DIFFERENT http sessions, as David suggested * the bean isn't actually session-scope (maybe you have multiple definitions for the same name, or a custom VariableResolver that has a bug...) * something is deleting it from the session after it is created Regards, Simon Michael Heinen wrote: > It is the same session id. > I have absolutely no idea what's going wrong internally. > > -----Original Message----- > From: David Delbecq [mailto:[EMAIL PROTECTED] > Sent: Donnerstag, 22.
