David, Thanks for your reply. How do you put the info into the form bean?
I use a action called "RegistrationUpdateOpenAction" to get the data from the database and forward to the view jsp (registrationUpdate.jsp), but I don't know how to put that data into the form bean for this ( the underlying form bean would be RegistrationUpdateForm). I'm confused as the form bean is created/recycled by Struts on opening the view. How do I get premptive access to it? Can I just create it and add it to the request scope? Won't struts create another one? Iain. Please respond to "Struts Users Mailing List" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] cc: Subject: Re: HOWTO pre-populate forms with data, then update ? Traditionally you do this: 1. GetMyFormAction determines if it's add or edit from a query string attribute. 2. For edit go get the info from db using the record's id you passed in the query string. 3. Put that info into your form bean. 4. Forward to your form The form's input elements will be prepopulated with data for the edit screen.
