You should use AjaxFormComponentUpdatingBehavior for this. Then you
can just get your model object. Your model object has to be something
that is update-able though. Currently you use a string, which is read
only. Do e.g. something like this:
public class SampleTextArea extends TextArea {
private String text;
public SampleTextArea(String id) {
super(id);
setModel(new PropertyModel(this, "text"));
add(new AjaxFormComponentUpdatingBehavior("onchange"){
protected void onUpdate(AjaxRequestTarget target) {
System.out.println("text: " + text);
}
});
}
public String getText(){ return text; }
public void setText(String text) { this.text = text; }
}
