struts2 ModelDriven
问题说明，我为使程序层次清晰，我使用了ModelDriven
但在执行updateReceive.action和createReceive.action时，程序还未执行toEditReceive方法，怎么就返加 INPUT了。
如果把result返回的input去掉报错
Could not find action or result
No result defined for action com.toone.cost.basework.receive.action.ReceiveAction and result input - action
我没使用validation
跟踪，actionType值已set到form对象中去了。
请高手指教，初学struts2

//BASEAction对象
public class BaseAction extends ActionSupport implements ModelDriven {
public static final String CREATE = "create";
public static final String EDIT = "edit";
public static final String LIST = "list";
public static final String VIEW = "view";
// form对象
protected BaseForm form = new BaseForm();
}

//action对象
public class ReceiveAction extends BaseAction {

public static final String FRAME = "frame";

public static final String PRINT = "print";

private ReceiveService receiveService;
....以上只是action部分代码
/////spring 配置
<bean name="receiveForm"
class="com.toone.cost.basework.receive.action.ReceiveForm"
scope="prototype">
</bean>

<bean name="receiveAction"
class="com.toone.cost.basework.receive.action.ReceiveAction"
scope="prototype">
<property name="receiveService" ref="receiveService" />
<property name="form" ref="receiveForm" />
</bean>

Struts2实现ModelDriven接口：

必须重写getModel方法

@Override
public Object getModel() {
return null;
}

你的Action中加入以下方法在尝试一下：
@Override
public ReceiveForm getModel() {
return receiveForm;
}
------解决方案--------------------
<property name="receiveService" ref="receiveService"
