I tried the following but couldnt get into "onUpdate" method while debugging.
I need to use checkgroup to be able to use
AjaxFormChoiceComponentUpdatingBehavior. So I created a checkgroup and added
the checkboxes into it. So I guess in each iteration I am creating one text
area, one check group and one checkbox that is attached to that checkgroup.
What I am trying to do is when I select a checkbox, I want to re-render only
the checkboxes by iterating the item list one by one. But it seems if I do
this I need to add ajaxbehaviour on to listview?? I think what I am trying
to do in here is a little bit tricky and this is not Listview is created for
am i right? I am definitely stucked. If I dont use Listview, I need to do
this by putting more lines of code and I dont want to do that.
ListView listView = new ListView("list", data)
{
@Override
protected void populateItem(final ListItem item) {
NameWrapper wrapper =
(NameWrapper)item.getModelObject();
item.add(new TextArea("name", new
PropertyModel(wrapper, "name")));
final CheckGroup checkgroup = new CheckGroup
("checkgroup", new PropertyModel(wrapper, "selected"));
item.add(checkgroup);
CheckBox check = new CheckBox("checkbox",new
Model());
checkgroup.setOutputMarkupId(true);
checkgroup.add(check);
checkgroup.add(new
AjaxFormChoiceComponentUpdatingBehavior() {
@Override
protected void onUpdate(AjaxRequestTarget
target) {
info("We are here");
for (Iterator iter = item.iterator();
iter.hasNext();) {
// FIND THE SELECTED ONE and DE-SELECT
the OTHER CHECKBOXES in the list
}
target.addComponent(checkgroup);
}
});
}
};
listView.setReuseItems(true);
add(listView);
