Title: Question on the ActionForm design for dynamic data?

(1) Have a Vector / Collection of contributors (ie. getContributors()) belonging to your form.  Inside that function, check to see if you need more rows by using code similar to the following:       public Vector getCustomerContacts()     {         CustomerContact lastCustomerContact = (CustomerContact)this.customerContacts.lastElement();         if (!lastCustomerContact.isEmpty())                                            // is this slot being used?             this.customerContacts.addElement(new CustomerContact());    // always have one available slot at the end of the matrix                      return this.customerContacts;     } (2) Do not use the reset() method.   (3) On your JSP, use code like this:     <% int i = 0; %>     <logic:iterate id="customerContact" name="adminUpdateProfileForm" property="customerContacts">        <tr>         <td class="smallFont"><input type='text' name="customerContact[<%= i %>].contactName" value="<%= ((com.domain.project.CustomerContact)customerContact).getContactName() %>"></td>         <td class="smallFont"><input type='text' name="customerContact[<%= i %>].contactTitle" value="<%= ((com.domain.project.CustomerContact)customerContact).getContactTitle() %>"></td>         <td class="smallFont"><input type='text' name="customerContact[<%= i %>].contactPhone" value="<%= ((com.domain.project.CustomerContact)customerContact).getContactPhone() %>"></td>        </tr>        <% i++; %>     </logic:iterate> (4) Have a button on the form "Add more rows" in which case the form posts to itself and will cause a new row to be added at the bottom of the grid.     Hope this help, Jeff   ----- Original Message ----- From: Joyce Tang To: [EMAIL PROTECTED] Sent: Saturday, May 19, 2001 11:28 PM Subject: Question on the ActionForm design for dynamic data? Here is the situation. I am developing a system to maintain a contribution plan.  I need to input the plan information first and add unlimited number of contributors, specifying each share of the plan.  So there will be a page with contribution plan information and a list of all the contributors.  The information you can edit on this page is the percentage of share of each contributor. Validation rules are: share need to add up to 100 and share figure is an integer between 0 and 100.   Since the number of contributors is unknown in advance, how should I design the ActionForm? Thanks a lot, Joyce
