RE: Populating complex java objects in forms - PROBLEM SOLVED, BUT IS THIS A BUG IN STRUTS?
There is no way in struts to populate the complex JAVA object with data simply from a submit form. If you pre-initialize your complex object then the submit form will be able to populate customer.name, customer.address.line1, customer.address.zip but ONLY if you have these in your form as valid properties. The method setCustomer(Customer c) or Customer getCustomer() will never be called because there is no such representation of a customer on the page. Because your form has a scope of request, it goes away after the request is complete. So, when you first show the customer on the screen, I presume, the Customer object is somehow found and populated and put into the form. At this point, the request is done and over with. The Customer object that you have created has been lost. When the user hits the submit button, a new request is created. Since this new request is calling on the action which requires a form, a NEW form is created with a NEW Customer member. If you initialized the customer to a new Customer(), then struts is able to match properties and put customer.name in to your customer name or customer.address.city in to the proper field, but it's NOT the same Customer object (pointer wise) that you have initially found. So, if you have other properties in the Customer object which are NOT shown on the page, then they will be reset to what ever they are when you do an initial new Customer. If you want to keep the same form, there are two things you can do: 1. Change the scope from request to session. This will keep the original form that you created, and since the original customer object that you have found and populated in to the form. Using this method, however, will probably require that your submit action, removes the data from the session. Otherwise, your session would contain variables which are no longer used (bad use of resources). 2. Pre-initialize the customer and all the objects inside of the customer just like you already did. This will populate the fields on your .jsp form back into the customer object, but not all the fields of the customer. Only those which are directly used on the form. These are the options I can think of. Hope this helps. - -AP_ See my profile at http://www.myprofiles.com/member/view.do?profileId=128 -Original Message- From: Charlesworth, Chico [mailto:[EMAIL PROTECTED]] Sent: Friday, March 08, 2002 2:41 AM To: 'Struts Users Mailing List' Subject: RE: Populating complex java objects in forms - PROBLEM SOLVED, BUT IS THIS A BUG IN STRUTS? I've found that my problem is that my Customer instance was not initialized in the Form class, but I wouldn't have thought this should be necessary in Struts. This then also means that any other complex java objects within customer would need to be instantiated (i.e. Address) and so on if Address had other complex java objects. So it works fine if in the form I define: Customer customer = new Customer(); Also, if I invoke an Action class and create a new instance of customer in the Customer form and then forward to the customer jsp, it displays the new instance values ok, but it still doesn't work when submitting the form if the Customer instance in the form is not instantiated (customer is null again).

RE: Populating complex java objects in forms
The scope is request, which should be ok, and other form fields that are Strings or String Arrays are populated ok, but not complex objects like Customer. Any other suggestions? -Original Message- From: Oliver Reflé [mailto:[EMAIL PROTECTED]] Sent: 07 March 2002 17:10 To: Struts Users Mailing List Subject: AW: Populating complex java objects in forms maybe check the scope of your form beans, maybe the one in the form is held in the session, and the one your action is expection should be in the request. If that happens struts generates a new form bean which is empty. -Ursprüngliche Nachricht- Von: Charlesworth, Chico [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 7.
