if my action determines that what is present in session is no more valid,
then it would clear this object from session. My interceptor has to check
and set the correct object in session after action has returned.
The setting in session has to happen after action invocation and before JSP
rendering.
Interceptor implementing PreResultListener did not work for me.
I could get it working with the following snippet.
invocation.addPreResultListener(new PreResultListener() {
});
Thank you,
JK.
