Hi, I'm exploring the new features of Struts 1.1 (using b2 release) and got stuck on the use of the combination DynaValidatorActionForm - List - nested tags (iterate, write).
CASE I am trying to build a search & list page. The search is a form with (for simplicity) one 'html:text' input field and a search button. The results of the search need to be displayed on the same page and be part of the same form. This list of results will be displayed as: a checkbox in the first column and a range of properties of the objects (e.g. Books) in the resultset in subsequent columns. The user will be allowed to select multiple items from the list for further processing. Think of a list of books, the user selects the books he/she wants and they are added to the shoppingcart. I would like to use a DynaValidatorActionForm with form-bean properties 'title' (java.lang.String) and 'books' (java.util.List). The search action handler uses the input from the title field to fetch the books from the database and sets this list of books in the 'books' field of the DynaValidatorActionForm. PROBLEM Doing the first search and display the results is no problem but on a new search request, the form can not be processed. I get a java.lang.NullPointerException: No indexed value for 'books[n]' (n being the size of the resultset of the first search). What could be the problem? -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
