THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
It's common to want the user to confirm his action if it would be hard to reverse, e.g. if he asked to delete something. Here's one way to do this, using Javascript:
Link removeLink = new Link("removeLink") {
@Override
public void onClick() {
// do something you want to confirm beforehand
}
};
removeLink.add( new SimpleAttributeModifier("onclick", "return confirm('are you sure?');"));
