Yes .
In the WebPage , I add MyPanel like this :
myPanel = new MyPanel("myPanel" , new PropertyModel(this , "myobj"));
myPanel.setVisible(false);
myPanel.setOutputMarkupPlaceholderTag(true);
add(myPanel);
And in the MyPanel :
public class MyPanel extends Panel
{
private MyObj myObj;
public MyPanel(String id , IModel model)
{
super(id);
this.myObj = (MyObj) model.getObject();
add(new Label("xxx" , myObj.getFieldX.toString()));
add(new Label("yyy" , myObj.getFieldY.toString()));
}
}
Because myObj passed to MyPanel is initially null ,
In the MyPanel construction time , myObj.getFieldX , myObj.getFieldY will
throw NPEs here...
I don't know how to solve it .....
