I want to add a tooltip behavior to a ContextImage in Wicket 1.5.5.
public class SimpleTooltipBehavior extends Behavior{
private String tooltip;
public SimpleTooltipBehavior(String tooltip) {
super();
this.tooltip = tooltip;
}
@Override
public void onComponentTag(Component component, ComponentTag tag) {
super.onComponentTag(component, tag);
tag.addBehavior(AttributeModifier.replace("alt", tooltip));
tag.addBehavior(AttributeModifier.replace("title", tooltip));
}
}
This does not work. The modifiers are not added to the markup.
But this works:
public class SimpleTooltipBehavior extends Behavior{
private String tooltip;
public SimpleTooltipBehavior(String tooltip) {
super();
this.tooltip = tooltip;
}
@Override
public void onComponentTag(Component component, ComponentTag tag) {
super.onComponentTag(component, tag);
tag.getAttributes().put("alt", tooltip);
tag.getAttributes().put("title", tooltip);
}
}
What is wrong with the first code?
