ComponentTag's behaviors are used/read before component's
behavior#onComponentTag() is called. I.e. you add them a bit late.
You can do it with:
public class SimpleTooltipBehavior extends Behavior{
private String tooltip;
public SimpleTooltipBehavior(String tooltip) {
super();
this.tooltip = tooltip;
}
@Override
public void onBind(Component component) {
component.add(AttributeModifier.replace("alt", tooltip));
component.add(AttributeModifier.replace("title", tooltip));
}
