Hello I read through several discussions about this problem but havent come to a conclusion on how to resolve it.
A very simple explanation of my problem I have two JSP pages. On page 1 - several account numbers are displayed. When a user selects a particular account, in my action class, I'm getting all the addresses associated with the account. All these address information is stored in beans (AddressBeans) and the beans are stored in an arraylist and the arraylist is part of my actionForm. Then the control is forwarded to my second jsp page, where I get this arraylist, iterate through it, get the individual address beans and display the information. On this page, for each address bean, I'm having some textboxes to capture information for that particular address. So I'm using indexed property. I submit the form and everything works fine. The problem comes when I open a new window from the first one. An example scenario - 1) On the first JSP page, I open an account which has say 2 Address Beans - so the second JSP page is displayed with 2 Address Beans. The arrayList property of the actionForm has 2 elements. 2) From this page - I open a link in a new window which takes me back to Page 1. Here I select another account which has say 1 Address Bean. The second page is opened and 1 address bean info is displayed. Now the arraylist property of ActionForm has been overridden and has 1 element. 3) Now I come back to my first window, where I was displaying 2 AddressBeans, fill in the information for the textboxes for each addressbean and click on submit and then I get this error javax.servlet.ServletException: BeanUtils.populate root cause java.lang.IndexOutOfBoundsException: Index: 1, Size: 1 Which is understandable. When ActionForm tries to fill the indexed properties for the 2 Addressbeans in the list, it finds only one element in the list. First of all, is my understanding of this problem correct. Secondly what is the best way for me to handle this problem. I've read people talk about overriding RequestProcessor class and create a new action form instance everytime. Any suggestions will be appreciated.
