hi, concerning nested properties, i found so many questions, hints etc. in the archive but nothing that really helped all the way...i'm still confused (or even more now...) i still don't understand how struts handles input from a form that holds an iteration of nested beans. is the following correct? as soon as the user submits the form, the actionform-bean, holding the nested beans with the user's changes, gets transmitted. is it so, that before the action-class is called, the form-bean's reset() method is called, and all nested beans are set to null by default? so do i have to override the reset() method? what do i iterate over in the reset() method to get the user's inputs? how do i limit the iteration? does the validate() method gets called before the reset method?.
i've seen examples, where a dto-class is instanciated within the reset() method. is this the way to do it? do i have to access these dto-beans in the action class? could somebody give me a little example of a reset()-method, just to show how the user's input can be gathered and then stored away? and.. what are lazy lists? i wasn't able to find a definition.... sorry about it but regards from an utterly confused martin ---------- Urspruengliche Nachricht ------------------------------ Von: <[EMAIL PROTECTED]> Datum: Mon, 19 Jan 2004 10:52:10 +0100 >You ahve a fixed length or Empty list in the form.So when the auto population tries >to populate the nested bean for the list which is empty/fixed size,you get this >exception. >Try to use lazy list or search the archive for nested property usage...There are many >examples which will demonatrate how to use it. > >HTH. >regards, >Shirish > >-----Original Message----- >From: Martin Sturzenegger [mailto:[EMAIL PROTECTED] >Sent: Monday, January 19, 2004 10:46 AM >To: Struts Users Mailing List; [EMAIL PROTECTED]; Struts Users >Mailing List >Subject: Re: Including one JSP in another > > >i try to receive user-input from a form using a list of nested beans. >after hitting submit i get an ArrayIndexOutOfBoundsException >can somebody give me a hint? >many thanks >martin > > > > >stacktrace: > >java.lang.ArrayIndexOutOfBoundsException > java.lang.reflect.Array.get(Native Method) > > org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:525) > > org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:428) > > org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.java:770) > org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:801) > org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:881) > org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) > org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1252) > > org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:821) > org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:254) > org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482) > org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525) > javax.servlet.http.HttpServlet.service(HttpServlet.java:763) > javax.servlet.http.HttpServlet.service(HttpServlet.java:856) > > > > >>> > > >>> > > Confidentiality Notice >>> > > >>> > > The information contained in this electronic message and any >>attachments >>> > > to this message are intended >>> > > for the exclusive use of the addressee(s) and may contain confidential >>> > > or privileged information.
