Hmmm. I have never put actual wicket Link objects as members of a List, so
it looks a little confusing. Anyway, you have not added the Link itself.
What you did was in effect "override" the <a> tag and made it a Label. The
wicket Link object itself does not have a getAddress() method. The
onClick() is called when the Link is clicked by the user. It is up to you to
do something at that point.
Important: I assume you created the Link objects with an ID = "link".
There is a couple ways to do this but the simplest would be:
Change your html:
<div wicket:id="list">
<a href="#" wicket:id="link"><span wicket:id="linkName">link<span></a>
</div>
Your code:
add(new ListView("list", new LinkDAO().allLinks()){
@Override
protected void populateItem(ListItem arg0) {
Link l = (Link)arg0.getModelObject();
l.add(new Label("linkLabel", l.getName());
arg0.add(l);
}
});
Adding the Link will override the href attribute to do a call to the
onClick() method you defined when you created each Link object. I assume
the onClick() method has the code that tells wicket what to do when the Link
is clicked - like go to to an address.
Generally, Link objects are created as anonymous inner classes. In this
scenario, you would not create Link objects in your List. Your List would
contain your label data to display, and what to do when the link is clicked.
add(new ListView("list", new LinkDAO().getLinkData()){
@Override
protected void populateItem(ListItem arg0) {
LinkDataObject linkData =
arg0.getModelObject();
Link l = new Link("link") {
public void onClick() {
// go somewhere or do something
....... linkData.getWhereToGo();
}
};
l.add(new Label("linkLabel",
linkData.getLabel());
arg0.add(l);
}
});
Hope this helps.
