Arg, I wanted to make my changes bold. But now I see stars. Not sure if
you get those too, but if you do: leave out the stars :)

we need to override two methods: onBeforeRender, which prepares for
rendering,
and convertInput, which handles receiving input."
So your code would become something like this:
public class LimitedTextArea extends FormComponentPanel implements
IHeaderContributor {
*private String text;
private TextArea textField;
* public LimitedTextArea(String id, IModel model, int limit) {
super(id, model);
* PropertyModel textModel = new PropertyModel(this, "text");*
*textField *= new TextArea("content", *textModel*);
add(textField);
...
}
*...@override
public void onBeforeRender() {
text = (String) getModelObject();
super.onBeforeRender();
}
@Override
public void convertInput() {
String text = (String) textField.getConvertedInput();
setConvertedInput(text);
}
*}
