Hi,
you'll have to tell the request target which components to redraw:
Put your list inside a markupcontainer and use addComponent().

In this post you said "You found it". Could you please post how did you
do it?
Zinovii
in addPanel()
replaced
panels.add(panel);
with
panels.getModelObject().add(panel);

Hi,
I'm trying to dynamically add components to an existing ListView but I
can't figure out how to do that. Here is my case:
MyPanelContainer class with markup
<wicket:panel>
<wicket:container wicket:id="panels">
<wicket:container wicket:id="panel" />
</wicket:container>
# add panel
</wicket:panel>
and here is how I create the container in the constructor of my page
..
MyPanelContainer container = new MyPanelContainer("panels_list_1");
List<MyPanel> panels = new ArrayList<MyPanel>();
for (int j = 0; j < 5; j++) {
MyPanel panel = new MyPanel("panel");
.....
panels.add(panel);
.
container.add(new ListView<MyPanel>("panels", panels) {
protected void populateItem(ListItem<MyPanel> item) {
item.add( item.getModelObject());
}
});
add(Container);
..
This works fine and I can see all MyPanel inside the container.
Now I'm trying to add another MyPanel inside the container on user
click. Here is the constructor of MyPanelContainer
public MyPanelContainer(String id) {
super(id);
....
add(new Link("addPanel") {
@Override
public void onClick() {
addPanel();
}
});
.
..
public void addPanel() {
ListView< MyPanel > panels = (ListView< MyPanel >)
get("panels");
MyPanel panel = new MyPanel("panel");
...
panels.add(panel);
}
Basically addPanel() does the same thing as in page constructor to add
panels to the list but nothing shows up.
Thanks in advance for your help
Ozkan
