Hi Olivier,
I simple way to achieve this is to have a (abstract) #onError method:
public abstract class MyModel extends
LoadableDetachableModel<List<MyObject>>
{
private static final long serialVersionUID = 1L;
private static final Logger LOG =
LoggerFactory.getLogger(DashboardModel.class);
public MyModel()
{
}
@Override
protected List<MyObject> load()
{
List<MyObject> list = new ArrayList<MyObject>();
try
{
//TODO fill list;
}
catch (TheException e)
{
this.error(e.getMessage(), e);
}
return list;
}
private void error(String message, Exception e)
{
LOG.error(message, e);
this.onError(message);
}
protected abstract void onError(String message);
}
In MyPage
private MyModel newMyModel()
{
return new MyModel() {
private static final long serialVersionUID = 1L;
@Override
protected void onError(String message)
{
MyPage.this.error(message);
}
};
}
Hope this helps,
Sebastien.
