Struts 1.2.9 Tomcat 5.0.28 Java 1.4.2 Basically, if the session times out or tomcat is restarted (I think re-start of the web app would probably do it) and sessions aren't being serialized (This happens when they are too I think) AND the app is left on a page with a form containing an indexed property, you get a stack trace submitting the form after tomcat is started (in the re-start case--session timeout--you just get the problem)--not a real good user experience. The issue is the form bean is nulled, er rather a new form bean is created because you have a new session presumably (the form bean is session scoped), but the properties map contains a reference to an indexed property like "schedule[0]". So, what happens is that using the property name from the map (schedule[0]), this property is accessed in the form bean to get the value, but the form bean has an empty ArrayList, so there is nothing but null at index 0. You get an IndexOutOfBoundsException. This problem only occurs on forms with indexed properties. I get my session timeout page when on any other form. Any help is appreciated.
