Hi,
I've also seen similar errors and I'm not sure why. Using JSF 2 it happens
quite often for ajax requests. I also have another issue and I'm not sure if
it's related to the same problem. The other issue is with jsf session beans.
If you're using client-side state saving and set some value to a session
scoped jsf bean the value is not stored! I think this happens because of
some optimization to how sessions are stored. I suppose updating a session
bean (which already exists in the session) doesn't mark session dirty during
the request and doesn't trigger session saving to storage after the request
completes. I've fixed this problem by adding:
MyBean bean =
(MyBeab)FacesContext.getCurrentInstance().getExternalContext().getSession(true)).getAttribute("bean");
((HttpSession)
FacesContext.getCurrentInstance().getExternalContext().getSession(true)).setAttribute("bean",
bean);
So basically just getting the bean from session and setting it back there
fixes the problem of saving changes to session beans using client-side state
saving.
