Outstanding! This sounds like exactly what I want. I'll check it out, and post back if I have any questions. Cheers! __ Do you Yahoo!? Yahoo!

RE: Form Bean Help?
Ok, that's fine, but why are you loading data from the database when you are performing an update operation? I think you'd want to first determine what sort of operation you are doing before assuming that you want to overlay what is currently in the Form with what is stored in your database. I guess what I'm saying is that, if you want to use the data that was posted, you shouldn't need to do anything... When I do an update and it fails, I just leave my ActionForm alone and the data that I posted is what stays there. I'm saying use an operation in your action to determine what your data operation is BEFORE assuming you want to modify your actionform... after all, you may want to revert to the old copy... I use my actionForm as a holding area to inspect and validate the data before moving it into my model tier. If my model update fails, then I leave the form alone and redisplay the old copy with the current form. Am I misunderstanding what you are trying to do perhaps? -Original Message- From: Matt E [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 29, 2003 12:46 PM To: Struts Users Mailing List Subject: RE: Form Bean Help?

RE: Form Bean Help?
My angle on this is to only load the data from the database when the user is submitted a request to "read" data. If they are submitting an "update" action, I don't load the data from the database. -Original Message- From: Matt E [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 29, 2003 12:37 PM To: [EMAIL PROTECTED] Subject: Form Bean Help? Hello All, I'm running into a little problem, maybe someone can help me fix it. My application is driven by filling out web forms. At one point, A user can click the "Save Form" button, which writes the form information to a Database. When the user visits the page again, the action builds a DTO that contains all the information they had filled out and puts it in the session scope, then forwards to the JSP page that has the form on it. I had been using the value property of the struts-html tags to fill in the data, but I've noticed that when the user hits submit, if there is a validation error, they are pushed back to the page, and the data they had enetered is replaced with what was in the DTO (which is now old data). I've also run into the problem of filling in things like radio buttons, based on what was in the DTO. It seems to me that what I want to do is not pass along the DTO with the action, but fill out parts of the Form Bean before forwarding to the page that displays it, at which point I could remove the value properties of the html tags, and have everything work. My question is, how can I do this from the action? Or do I want to attack this problem in another way? Thanks! __ Do you Yahoo!? Yahoo!
