I want to make a form with "Add" button. After pressing "Add" button new panel adds to the wicket ListView element. How do I do that? I want to be able add unlimited number of rows.
EDIT:
InteractivePanelPage.html
<table>
<tr>
<td><a href="#" wicket:id="addPanelLink">Add Panel</a></td>
</tr>
<tr wicket:id="interactiveListView">
<td>
<span wicket:id="interactiveItemPanel"></span>
</td>
</tr>
</table>
InteractivePanelPage.java
// ... imports
public class InteractivePanelPage extends WebPage {
public LinkedList<InteractivePanel> interactivePanels = new LinkedList<InteractivePanel>();
private ListView<InteractivePanel> interactiveList;
public InteractivePanelPage() {
add(new AjaxLink<String>("addPanelLink") {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
try {
System.out.println("link clicked");
InteractivePanel newInteractivePanel = new InteractivePanel(
"interactiveItemPanel");
newInteractivePanel.setOutputMarkupId(true);
interactiveList.getModelObject().add(newInteractivePanel);
} catch (Exception e) {
e.printStackTrace();
}
}
});
interactivePanels.add(new InteractivePanel("interactiveItemPanel"));
interactiveList = new ListView<InteractivePanel>("interactiveListView",
new PropertyModel<List<InteractivePanel>>(this, "interactivePanels")) {
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem<InteractivePanel> item) {
item.add(item.getModelObject());
}
};
interactiveList.setOutputMarkupId(true);
add(interactiveList);
}
public List<InteractivePanel> getInteractivePanels() {
return interactivePanels;
}
}
InteractivePanel.html
<html xmlns:wicket>
<wicket:panel>
<span><input type="button" value="BLAAA" wicket:id="simpleButton"/></span>
</wicket:panel>
</html>
InteractivePanel.java
// ... imports
public class InteractivePanel extends Panel {
private static final long serialVersionUID = 1L;
public InteractivePanel(String id) {
super(id);
add(new Button("simpleButton"));
}
}
This simply doesn't work. Can anybody see why? Thanks
