Where do you use a CompoundPropertyModel?
For your problem you have several solutions.
Here is 2 of them :
1) - With the CompoundPropertyModel
class MyModel {
private String text;
public MyModel(String text) {
this.text = text;
}
public String getText(){
return text;
}
public void setText(String text) {
this.text = text;
}
}
class MyPanel extends Panel{
public MyPanel(String id, MyModel myModelObject){
super(id, new CompoundPropertyModel(myModelObject));
add(new TextField("text")); // the TextField id must be the name of your
object property
(...)
}
}
MyModel myModelObject = new MyModel("hello");
add(new MyPanel("textPanel", myModelObject);
2) - With the PropertyModel
class MyModel {
private String text;
public MyModel(String text) {
this.text = text;
}
public String getText(){
return text;
}
public void setText(String text) {
this.text = text;
}
}
class MyPanel extends Panel{
public MyPanel(String id, MyModel myModelObject){
super(id);
add(new TextField("panelField", new PropertyModel(myModelObject,"text")));
(...)
}
}
MyModel myModelObject = new MyModel("hello");
add(new MyPanel("textPanel", myModelObject);
Enjoy :-)
