yep I did it like that and it works
public class Editor extends FormComponentPanel<List<String>> {
private ListView<String> item;
/**
* If you dont have ArrayList you can always copy your collection to new
ArrayList.
*
* @param id of the control
* @param accounts a list of all accounts assigned to the peron.
*/
public Editor(String id, IModel items) {
super(id, items);
buildComponents();
}
private void buildComponents()
{
setOutputMarkupPlaceholderTag(false);
add(new SimpleAttributeModifier("class", "editor-panel"));
final List<String> items = getModelObject();
item = new ListView<String>("item", items){
@Override
protected void populateItem(ListItem<String> listItem)
{
String number = listItem.getModelObject();
listItem.add(new NumberInput("number", number));
listItem.add(new RemoveButton("remove", number, items));
}
};
item.setReuseItems(true);
Link addButton = new Link("add"){
@Override
public void onClick() {
items.add("");
item.detach();
}
};
add(addButton);
add(item);
}
@Override
protected void onComponentTag(ComponentTag tag) {
tag.setName("section");
super.onComponentTag(tag);
}
@Override
protected void convertInput()
{
setConvertedInput(saveConvertedData());
}
private List<String> saveConvertedData()
{
final List<String> items = new ArrayList<String>();
item.visitChildren(NumberInput.class, new
Component.IVisitor<NumberInput>(){
@Override
public Object component(NumberInput component) {
String number = component.getConvertedInput();
items.add(number);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return items;
}
}
