Hi,
Here is a simple Behavior that adds "has-error" CSS class to any component
that has an error feedback message:
public class ErrorBehavior extends Behavior {
@Override
public void onComponentTag(Component component, ComponentTag tag) {
FeedbackCollector feedbackCollector = new
FeedbackCollector(component);
List feedbackMessageList =
feedbackCollector.collect(new
ErrorLevelFeedbackMessageFilter(FeedbackMessage.ERROR));
if (CollectionUtils.isNotEmpty(feedbackMessageList)) {
tag.append("class", "has-error", " ");
}
}
}
You can add it to all FormComponents with IComponentInstantiationListener:
public static class InstantiationListener implements
IComponentInstantiationListener {
@Override
public void onInstantiation(Component component)
{
if (component instanceof FormComponent)
{
component.add(new ErrorBehavior());
}
}
}
In YourApplication#init(): getComponentInstantiationListeners().add(new
InstantiationListener())
