If you have a form linked to a bean using key attribute, then when you submitted, must you instantiate the bean before the call action populate the properties? Or Strust2 instantiate automatically after you call the action.
<form action=“a”> <s:textField key=“bean.t”/> <submit/> //The method execute of the A class action public class A extends AcctionSupport{ private Object bean; public String void execute(){ //Call business logic method control(bean); return SUCCESS; } } This throws a NullpointerException???
