Rick: I think the problem is in how you are initializing your objects. In particular the problem is where you call the setCarList() method. Both Persons are getting a reference to the same list. In other words you have only one car list in memory. So, when you modify it, you are modifying the car list for both persons.
Make sense? Aside: Try not to initialize your bean in the reset() method. It gets called each time the form is submitted before Struts sets the values the user provided. Can you somehow, move that logic to the Action class?

What is odd is something goes wrong during the process of being submitted to the action. The action does as you mention..just forward back to the same location: public ActionForward getResults(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { String forward = "continue"; NestingForm f = (NestingForm)form; request.setAttribute(mapping.getAttribute(), f); return mapping.findForward(forward); } The odd thing is if you cycle through the ArrayList of people in this action and print out what you get you find all indexes populated with the whatever Person object is in index 0 of people. I tested the above with this: ArrayList people = f.getPeople(); for ( int i = 0; i< people.size(); i++ ) { Person person = (Person)people.get( i ); Logging.info("\nName: "+person.getName() ); ArrayList carList = person.getCarList(); for ( int n = 0; n < carList.size(); n++ ) { CarBean car = (CarBean)carList.get( n ); Logging.info(" Car: "+car.getCarName()+" - "+car.isCarSelected() ); } } So the problem is somehow from whatever is going on 'behind the scenes' from when submit is called, then reset, then to the action. I've tried just about everything in the reset method of the form. Currently for debugging and I'm going through in the reset and repopulating everything just like I do in the first action that sets up the page. I figured this would be ok since I thought when I submit and after reset is called then everything in the jsp form overwrites whatever the reset did? In the reset method I'm doing this: ArrayList cars = new ArrayList(); CarBean car = new CarBean(); car.setCarName("Mustang"); car.setCarSelected(false); cars.add(car); car = new CarBean(); car.setCarName("Mercedes"); car.setCarSelected(false); cars.add(car); car = new CarBean(); car.setCarName("Porsche"); car.setCarSelected(false); cars.add(car); //normally get form business layer people = new ArrayList(); Person person = new Person(); person.setName("Juan"); person.setCarList(cars); people.add(person); person = new Person(); person.setName("Rick"); person.setCarList(cars); people.add(person); person = new Person(); person.setName("Jeff"); person.setCarList(cars); people.add(person); setPeople(people); SS> Does your form-bean do anything in the reset and/or validate SS> methods? No validation is being done. Reset is as above. Thanks so much for helping debug this.
