Re: dynamically adding components to a ListView
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
# add panel
and here is how I create the container in the constructor of my page
..
MyPanelContainer container = new MyPanelContainer("panels_list_1");
List panels = new ArrayList();
for (int j = 0; j < 5; j++) {
MyPanel panel = new MyPanel("panel");
.
panels.add(panel);
.
container.add(new ListView("panels", panels) {
protected void populateItem(ListItem 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

Re: dynamically adding components to a ListView
It doesn't create new panel on addPanelLink click.

Re: dynamically adding components to a ListView
panels.getModelObject().add(panel);
panels is ArrayList and it doesn't have getModelObject() method.

Re: dynamically adding components to a ListView
You are putting view objects inside the model of other view object. Models
are meant to keep your application domain data, and over that you create
your view. So:
For what MyPanel was designed?
1 - For present MyData
container.add(new ListView("panels", panels) {
protected void populateItem(ListItem item) {
item.add( new MyPanel("panel", item.getModelObject()));
}
});
then you write:
panels.getModelObject().add(new MyData());
more some code to update panels like
target.addComponent(container);
2 - For present some static markup on template
so consider to use an less sophisticated repeater, like RepeatingView

Re: dynamically adding components to a ListView
Hi, guys.
Just use PropertyModel.
Instead of this:
container.add(new ListView("panels", panels) { ... }
use this
container.add( new ListView>( this, "panels" ) ) { ... }
where 'this' is referenced to instance of class that contains list of panels
as it's property.
And check PropertyModel description at Doc API.
Best regards, Alexander.

in addPanel()
replaced
panels.add(panel);
with
panels.getModelObject().add(panel);

dynamically adding components to a ListView
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
add panel
and here is how I create the container in the constructor of my page
...
MyPanelContainer container = new MyPanelContainer("panels_list_1");
List panels = new ArrayList();
for (int j = 0; j < 5; j++) {
MyPanel panel = new MyPanel("panel");
.
panels.add(panel);
}
container.add(new ListView("panels", panels) {
protected void populateItem(ListItem 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
