Hello Pierre,
You can also just override/extend the onComponentTag function from the
Component.:
Component {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put("attribute", "value")
}
}
As far as I can see, SimpleAttributeModifier doesn't exist anymore, just use
the "AttributeModifier" class or sub-class that if you really need to.
Or attach a custom Behavior to the component which can also override the
onComponentTag function like so:
public class FeedbackFieldDecorator extends Behavior {
@Override
public void onComponentTag(Component component, ComponentTag tag) {
if (!((FormComponent<?>)component).isValid()) {
String cl = tag.getAttribute("class");
if (cl == null) {
tag.put("class", "error");
} else {
tag.put("class", "error " + cl);
}
}
}
}
Cheers,
Marco
