Thanks Timo...
I tried something similar to this .. It works.
Java :
======
txtAge = new TextField("txtAge", new Model(""));
lblModel = new ErrorLabelModel();
lblAgeValidate = new Label("lblAgeValidate", lblModel);
lblAgeValidate.setOutputMarkupId(true);
txtAge.add(new AjaxFormComponentUpdatingBehavior("onkeyup") {
protected void onUpdate(AjaxRequestTarget target) {
lblModel.setErrorMessage(txtAge.getValue());
target.addComponent(lblAgeValidate);
}
});
ErrorModel:
========
public class ErrorLabelModel extends Model {
public ErrorLabelModel() {
errorMessage = DEFAULT_ERROR_MESSAGE;
}
public void setErrorMessage(String _errorMessage) {
if (_errorMessage == null) {
errorMessage = DEFAULT_ERROR_MESSAGE;
} else {
errorMessage = _errorMessage;
}
}
public Object getObject() {
return errorMessage;
}
private String errorMessage;
private static final String DEFAULT_ERROR_MESSAGE = "";
}
The question is - can this be the fastest way of doing this...
