May be in the reset you have emptied the list.. Have a look at ListUtils.lazyList..That may solve your problem...
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, October 16, 2003 5:57 PM To: [EMAIL PROTECTED] Subject: ArrayIndexOutOfBoundsException after resubmitting form Hi all, I've searched the archive, but haven't found an occurrence of the exact same problem I am encountering. Here is a description of the problem: My intention is to use transactional tokens to prevent duplicate posting of a form where a user deletes a row in a list of search results. After the delete is successful, I use the browser's back button to return to the list of search results and attempt to submit the request to delete the same row again. At this point, an ArrayIndexOutOfBoundsException is thrown (the exception stack trace is provided below). After examining the debug log statements, it appears that the logic to validate the transactional token in the action has not yet been reached. The debug log statements indicate that the form's reset method is invoked and the getter for the list is called, but that is where it fails. The Struts logic is attempting to go past the last valid index in the list and I have not found a way to catch this nor prevent it. If anyone has any ideas, it would be much appreciated. Thanks in advance, Christina Here is the Exception Stack Trace: >>>>> com.ibm.servlet.engine.webapp.WebAppErrorReport com.ibm.servlet.engine.webapp.WebAppErrorReport: BeanUtils.populate at
