I didn't say "do the configuration in the instantiation listener". I
said "automagically add this [AutoConfigureBehavior mentioned in
previous sentence] to all components".
Example:
class AutoConfigureBehavior extends AbstractBehavior {
@Override
public void onComponentTag(Component component, ComponentTag tag) {
super.onComponentTag(component, tag);
if (component instanceof FormComponent<?> &&
!Strings.isEmpty(tag.getAttribute("required"))) {
((FormComponent) component).setRequired(true);
}
}
}
class AddAutoConfigureBehaviorToAllComponents implements
IComponentInstantiationListener {
@Override
public void onInstantiation(Component component) {
component.add(new AutoConfigureBehavior());
}
}
