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)); } > > > > -- > View this message in context: > http://apache-wicket.1842946.n4.nabble.com/ContextImage-and-tooltip-behavior-tp4544817p4544817.html > Sent from the Users forum mailing list archive at Nabble.com. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > -- Martin Grigorov jWeekend Training, Consulting, Development http://jWeekend.com --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
