> hi all,
> i am a beginner of struts2.
> i added a new struts2 project. below is the code.
> property in JSP page
> <s:form action="addBike">
> 	bike name <s:textfield name="bike.name" />
> 	color<s:textfield  name="bike.color" />
> 	size<s:textfield  name="bike.size" />
> </s:form>
> Java code,
> 	public class Bike {
> 	private String name;
> 	private String color;
> 	private String size;
> 	public Bike() {
> 		System.out.print("creating a new bike");
> 	}
> 	
> 	**getter and setter methode**
> }
> public class AddBikeAction extends ActionSupport implements ModelDriven {
> 	
> 	private Bike bike
> 	public AddBikeAction() {
> 	}
> 	public void setBike(Bike bike) {
> 		this.bike = bike;
> 	}
> 	public String execute() {
> 		System.out.print(bike.getName);
> 		System.out.print(bike.getColor);
> 		System.out.print(bike.getSize);
> 		return SUCCESS;
> 	}
> 	
> 	public People getModel() {
> 		return bike;
> 	}
> }
> when i submit this JSP page with 
> bike name = 'bike name', 
> color = 'red',
> size = '67'
> this console log is
> creating a new bike
> creating a new bike
> creating a new bike
> null
> null
> 67
> i am confused why it always create a new Bike object when each time setting the property.
so i only can get a Bike object with one not null property.
> i want to know what's wrong in my code or i was missing some config. so i got this issue.
> thanks,
> Alex
