RE: Passing an ArrayList
+1 I'm betting that this could be resolved by stashing the ArrayList into the request as an attribute or something similar, but would like some commentary on this issue. Dont take that bet. You will lose. Once the response is written out to the browser its gone. Dead. Extinct. Nailed to its perch and pining for the fjiords. And any attributes and parameters it had are gone too. You should to put it in the session. This is what the session is there for. No session. No store. End of story. (ok you could put it in the db (ok) or servlet context (dont), but... have fun managing it. ;-> ). If you really must share the session with other users, you would need to store it in the session under a unique id and have that unique id written to the html and submitted back in a hidden field so you can find it again! (That technique incedentally is also good if you need to support multiple browser windows for the same user too - something thet doesnt work too well with a constant session key.) Dont forget to clean it up (in session or db or wherever) after you have finished with it. Can you explain why you have multiple users with the same sessionId? That seems rather odd. -Original Message- From: Michael McGrady [mailto:[EMAIL PROTECTED] Sent: Tuesday, 10 February 2004 04:06 To: Struts Users Mailing List Subject: RE: Passing an ArrayList You have to store the information somewhere.

The user then clicks on a button to submit these to an Action. These 4 values are used to create an object that is added to an ArrayList. The page used for data entry is refreshed with the just entered values appearing as a row in a table. The user may do this as many times as they wish. My problem is that the ArrayList is recreated every time the Action is called. I understand that this a characteristic of the transient nature of Actions. Can anyone make any recommendations on possible ways to preserve this ArrayList between calls to the Action. I'm betting that this could be resolved by stashing the ArrayList into the request as an attribute or something similar, but would like some commentary on this issue.

RE: Passing an ArrayList
You really want to stick the data in session scope - that is what it is for. Request scope really won't help - anything in there will have gone out of scope immediately after the page is rendered for the user. I'd *seriously* question why you aren't supposed to be using session scope. Can you give us an idea why you are being asked to avoid it's use? If you can't use session scope then I think the only place you can store the data is the rendered html. You could use hidden input fields to store the data - these values will then be provided to the action then next time it is called. I think you should look at indexed properties - I haven't used them myself.
