Re: Implementation of new row functionality of HTML table in Struts

[Irfan Shaikh]

I am getting same error when i submit the form having newly added row.
Error is :

javax.servlet.ServletException: BeanUtils.populate
        org.apache.struts.util.RequestUtils.populate(RequestUtils.java:495)
        
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:804)

Here is the reset() method:

   public void reset(ActionMapping mapping,HttpServletRequest request) {
                System.out.println("reset called");
                int count=0;    
                if (null!=this.customer) {
                        String value = 
request.getParameter("customer[0].firstName");
                        System.out.println("value :" + value);                  
                if (value != null) {
                        while ((value = request.getParameter("customer[" + 
count +
"].firstName")) != null) {
                             System.out.println("value :" + value);
                             count++;
                        }
                }       
                
                Customer[] customers = new Customer[count];
                System.out.println("Customer[] size :"+customers.length);
                ListTextActionForm f = new ListTextActionForm();
                f.setCustomer(customers);
                
        } else {
                        System.out.println("Customer[] is null");
                }               
   }

No error arise  if no new row is added and code work fine.
