That's not it. I still get same error. I thought when the form is submitted, Strut will re-construct the collection of objects with values from the input form. Therefore, I don't have to specify the Collection/List size in the form bean constructor.

When you submit your form, the Struts controller finds what form bean is associated with it and constructs an instance of that form. It then starts assigning values to it, using the accessor methods. For indexed properties, it uses an accessor to retrieve a collection of objects, then gets the object indicated by the index from the collection, then uses an accessor method in that object to assign a value. And there's your problem. If your form bean's constructor doesn't create a collection with enough items in it, the struts controller will try to access a non-existent member of the collection at this point. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ------------------------------------------------------------------------------ Notice: This e-mail message, together with any attachments, contains information of Merck & Co., Inc.
