alex pan updated WW-2578:
-------------------------

    Description: 
hi all,

i am a beginner of struts2.

i added a new struts2 project. below is the code.

property in JSP page
	
	bike name <stl:textfield name="bike.name" />
	color<stl:textfield  name="bike.color" />
        size<stl:textfield  name="bike.size" />

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 access AddBikeAction, this console log is

creating a new bike
creating a new bike
creating a new bike
null
null
67(i input in JSP page)

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
