Thanks for your answer.

As I told you before, I deal with the ArrayList property of a bean which is already in session. My problem is I don't actually realize what is the object which is submitted by the form. You told it is the ArrayList itself, but how is it mapped onto the (Dynamic) form I've defined in stuts-config.xml? I don't understand why I get the IndexOutOfBoundsExceptions. It seems the ArrayList which is passed to the form-bean is null or empty. thanks -- Paride Perazzolo [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
