Hello again,
Actually I have created a behavior that automatically add labels and
validation messages for all my formComponents:
@Override
public void beforeRender(Component component) {
FormComponent formComponent = (FormComponent)component;
if (formComponent.getLabel() == null) {
logger.error("skipping, because no label set for " + component);
return;
}
formComponent.setOutputMarkupId(true);
Response response = formComponent.getResponse();
String markupId = formComponent.getMarkupId();
if (formComponent instanceof MyDateField) {
MyDateField dateField = (MyDateField) formComponent;
markupId = dateField.getInnerMarkupId();
}
response.write("<label for=\"" + markupId + "\">");
response.write(formComponent.getLabel().getObject());
// render validation message, if there is any
if (!formComponent.isValid()) {
String error = getFeedbackMessage(formComponent);
response.write("<strong>" + error + "</strong>"
);
}
response.write("</label>");
}
As you can see, I have created a copy of DateField and added a method
for returning the markupid of the 'main' component:
public String getInnerMarkupId() {
return dateField.getMarkupId();
}
Please let me know if there's a better solution.
And whether it would make sense to add this method to
FormComponentPanel so that subclasses can override it to return the
markupid of their 'main' formcomponent ?
regards,
Maarten
