How to delete an item from List view.
Hi All,
I have rendered a list view on a Web Page.
vehicle1 X
vehicle2 X
vehicle3 X
when a person click on 'X', that item should be deleted.
But I'm facing an issue, when i click on 'X', last item get deleted.
Actually when I delete vehicle2 from my list, it deletes vehicle2 but that
component is still there.
So while rendering it render vehicle1 & vehicle2.
public void onSubmit() {
List vehicles = (List) getParent().getParent().getModelObject();
vehicles.remove(index);
}
can please help out ??

Hi Johan,
Actually that's not a main button of my page.
So default processing is set false, bcz of that the values will not be there
in model objects.

Pankaj...

Re: How to delete an item from List view.
Posted by prati <pr...@gmail.com>.
Hi,
I am also having similar issue, it all the time removes last row.
I have attached code.
OptionGroupPageForm(String id) {
super(id);
final MarkupContainer rowPanel = new WebMarkupContainer("rowPanel");
rowPanel.setOutputMarkupId(true);
add(rowPanel);
// List all rows
rows.add(new String());
RefreshingView lv = new RefreshingView("rows") {
@Override
protected Iterator<IModel> getItemModels()
{
List models = new ArrayList();
for(int i=0;i<rows.size();i++){
models.add(new Model( (String) rows.get(i)));
}
return models.iterator();
//return rows.iterator();
}
@Override
protected void populateItem(final Item item) {
int index = item.getIndex() + 1;
item.add(new Label("index", "Option"+index + "."));
TextField text = new TextField("text", item.getModel());
RadioChoice rc = new RadioChoice("status", STATUS);
item.add(text);
item.add(rc);
item.add(new AjaxLink("removeRow") {
@Override
public void onClick(AjaxRequestTarget target) {
if (target != null) {
target.addComponent(rowPanel);
}
}
} );
}
};
lv.setItemReuseStrategy(ReuseIfModelsEqualStrategy.getInstance());
rowPanel.add(lv);
AjaxSubmitLink addLink = new AjaxSubmitLink("addRow", this) {
@Override
public void onSubmit(AjaxRequestTarget target, Form form) {
rows.add(new String());
if (target != null)
target.addComponent(rowPanel);
}
};
addLink.setDefaultFormProcessing(false);
add(addLink);
}
Thanks

You do use a delete button, so i guess the values are submitted.
Then if you store those first in the model objects you won't loose anything

Re: How to delete an item from List view.

wasn't the quickest solution:
public void onSubmit() {
List vehicles = (List) getParent().getParent().getModelObject();
vehicles.remove(index);
listView.removeAll();
}
Then if the list itself is stable on the server side (if other persons can
also delete or add stuff to that list you really should do it differently)
that should work fine. After you alter the listviews model you have to
remove all the items so that it will rebuild

Instead of using ListView, you could consider RefreshingView with it's
itemReuseStrategy set to ReuseIfModelsEqualStrategy.

it go away.. Sure there are somethinges you need to be aware of when

Not true. There are perfectly complete replacements for ListView, not
for the other things you mention.

If anytime someone comes along with a misunderstanding of a valid component
we don't have a framework left:
- models
- drop down choice
- urls
- mounting
All those things can be deprecated then.

Don't be too harsh. There have been quite a few people who wrote for
the WIKI before, and to be honest, I haven't always shared my
experiences with e.g. Hibernate with the rest of the world either.
How about a reconsideration of depreciating ListView?

well, thats the problem. you say you are not the right person because
you dont know. and that is the excuse a lot of users give for not
writing the wiki page. but guess what, after we help them here and
they do understand how listview works - they still dont come back and
write the wiki page.
so there you go, welcome to open source...

Re: How to delete an item from List view.
Posted by Alan Romaniuc <a....@gmail.com>.
Hi all,
I know that will be sound a little stupid, but ListView causes a lot
of problems for newbies (including reuse startegy). Maybe a better or
more "in depth" wiki entry would avoid these questions on this mail
list? Just a suggestion (once i am facing the same probles, i would
not be the right person to do that :( )

Re: How to delete an item from List view.
Posted by Igor Vaynberg <ig...@gmail.com>.
for the strategy to work properly you have to implement
equals/hashcode on the model, looks like you are just doing:
new Model( (Vehicle) ((List)getModelObject()).get(i))
Model does not implement equals/hashcode

Re: How to delete an item from List view.
Posted by pnerkar <pn...@gmail.com>.
Ya I tried refreshingview with ReuseIfModelsEqualStrategy,
But the data entered on page get cleared.
My new code is -
final VehiclesList vehicles = new VehiclesList("vehicles", new
PropertyModel((RatingRequestAuto)getModelObject(),"vehicles"));
vehicles.setOutputMarkupId(true);
vehicles.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());
add(vehicles);
private static class VehiclesList extends RefreshingView {
public VehiclesList (String id, PropertyModel model) {
super (id,model);
}
/**
* Return an iterator over models for items in the view
*/
protected Iterator getItemModels()
{
List models = new ArrayList();
for(int i=0;i<((List)getModelObject()).size();i++){
models.add(new Model( (Vehicle) ((List)getModelObject()).get(i)));
}
return models.iterator();
}
protected void populateItem(final ListItem item)
{
item.add(new TextField("vehicle.modelText", new
PropertyModel(vehicle, "model")).setRequired(true));
TextField registrationnumber = new
TextField("vehicle.registrationnumber", new PropertyModel(vehicle,
"registrationNumber"));
TextField engineNumber = new TextField("vehicle.enginenumber", new
PropertyModel(vehicle, "engineNumber"));
final int index = item.getIndex();
Button remVehBtn = new Button("btn_removeVeh", new ResourceModel(
"removevehicle" )) {
public void onSubmit() {
item.getParent().remove(item);
}
});
}
}
}
forgive me this may not be a cleaner way... I dont have more than a month
exp of wicket.

Re: How to delete an item from List view.
Posted by pnerkar <pn...@gmail.com>.
Hi Igor,
Finally I'm able to find out the exact issue.
suppose There are 3 items in the list-
wicket will assign id as 0, 1 & 2. to those items.
So When we say item.getparent().remove(item) to item with id=1,
them It'll remove that item from list but item with id=2 will not remain as
it is..
i.e. Now list will have 2 items one with id=0 & id=2.
So when we display list, it'll clears the fields for item with id=1.
so we need to update id field of item object... But think there is no way to
do that...
is there...???

Re: How to delete an item from List view.

Hi igor,
But If I remove setReuseItems(true), it'll remove all field values which
user has entered will be removed.
Bcz default processing is false for Remove button (Sorry forget to tell
you)
I just want to remove vehicle2, but the values entered for vehicle1 &
vehicle3 should not be lost.

Re: How to delete an item from List view.
Posted by pnerkar <pn...@gmail.com>.
Hi,
Following is my code for rendering vehicle list-
final VehiclesList vehicles = new VehiclesList("vehicledetails",
((RatingRequestAuto)getModelObject()).getVehicles());
vehicles.setOutputMarkupId(true);
vehicles.setReuseItems(true);
add(vehicles);
private static class VehiclesList extends ListView {
public VehiclesList (String id, List vehicles) {
super (id, vehicles);
}
protected void populateItem(final ListItem item)
{
item.add(new TextField("vehicle.modelText", new
PropertyModel(vehicle, "model")).setRequired(true));
TextField registrationnumber = new
TextField("vehicle.registrationnumber", new PropertyModel(vehicle,
"registrationNumber"));
TextField engineNumber = new TextField("vehicle.enginenumber", new
PropertyModel(vehicle, "engineNumber"));
final int index = item.getIndex();
Button remVehBtn = new Button("btn_removeVeh", new ResourceModel(
"removevehicle" )) {
public void onSubmit() {
List vehicles = (List) getParent().getParent().getModelObject();
vehicles.remove(index);
}
});
}
}
Thanks a lot for ur reply :)

if you want to talk about a cleaner way...
add(new removelink("remove", item.getmodel()) {
onclick() {
vehicles.remove(getmodelobject());
}
}
assuming vehicles is a property on listview's parent...

As a cleaner way to do this you could try
List<Vehicle> vehicles = findParent(VehiclesList.class).getModelObject();
