unselected choices of Palette contain duplicates ...
I have overriden the onEvent method of the Palette class in the attempt to
populate the palette (on the unleselected choices side) with data from
another component (an autocomplete) on the same page. THe only problem I
have is that the unselected choice side of the palette shows a duplicate of
the object I am trying to add. I cannot understand why twice ... ANy
suggestion ?
@Override
public void onEvent(IEvent<?> event) {
super.onEvent(event);
if (event.getPayload() instanceof MyUpdate){
MyUpdate update = (MyUpdate)event.getPayload();
Collection choices= this.getChoices();
choices.add(update.getModelObject());
this.getChoices().retainAll(choices);
update.getTarget().add(this);
}
}
}

The model is updated after a submit or an ajax event.
You need to choose and to implement it.

So, what do I do to update the palette's model with the changes before
target.add(this) ?

Re: unselected choices of Palette contain duplicates ...
Posted by Francois Meillet <fr...@gmail.com>.
if you push the submit button before sending any event, you will see that changes made to the model are saved correclty.
But in case you fire any event, you redisplay 'this' (the palette) before the model is updated.
The state of this, in that case, is like a new original palette.
So far, only the javascript on the client side has been executed.

I sort of got it to work, but now when I move items from one side of the
palette to the other and try to save it, the changes are not picked up by
the model and are not saved ...
public class MyPalette extends Palette {
private List<T> unselectedChoices;
public MyPalette(String id, IModel<List<T>> model,
IModel<List<T>> choicesModel, IChoiceRenderer<T> choiceRenderer,
int rows, boolean allowOrder) {
super(id, model, choicesModel, choiceRenderer, rows, allowOrder);
setOutputMarkupId(true);
unselectedChoices = new ArrayList<T>();
}
@Override
public void onEvent(IEvent<?> event) {
super.onEvent(event);
if (event.getPayload() instanceof MyAutoCompleteUpdate) {
MyAutoCompleteUpdate update = (MyAutoCompleteUpdate) event
.getPayload();
Collection collection = this.getChoices(); // the whole set of data,
availalble (unselected) and associated (selected)
System.out.println("SIZE " + collection.size() + " ");
unselectedChoices.add((T) update.getModelObject());
System.out.println("SIZE UNSELECTED" + unselectedChoices.size() + " ");
collection.addAll(unselectedChoices);
System.out.println("SIZE AFTER ADDING selection" + collection.size() + "
");
update.getTarget().add(this);

-Can you dump getChoices() after the line this.getChoices().retainAll(choices)
-also can you check your PaletteRenderer

In the onEvent method, update.getModelObject() is added to the choices collection.
The collection is not a Set, but a List.
So each time you add an item to choices, you create a new entry.

Re: unselected choices of Palette contain duplicates ...

To summarize that long code posting, on the page, there is an autocomplete,
and a form containing the palette.
The autocomplete "sends" the choice selection to the palette ... or is
there something else (the form ?) that receives the event first and sends it
to the palette ?

Let me see if I can give you a succinct version. THank you for trying to
help me understand.
public class MyPage extends MyCustomizedWebPage {
public MyPage () {
add(new PageHeaderComponent("pageheader", "myPage"));
add(new Label("title", PAGE_TITLE));
add(new AjaxLazyLoadPanel("myAutoCompletePanel") {
@Override
public Component getLazyLoadComponent(String markupId) {
return new MyPanel(markupId);
}
@Override
public Component getLoadingComponent(String markupId) {
// TODO Auto-generated method stub
return new MyLoadingComponent(markupId);
}
});
Form form = new Form("form");
final FeedbackPanel feedbackPanel = new
FeedbackPanel("feedbackPanel");
feedbackPanel.setOutputMarkupId(true);
form.add(feedbackPanel);
final MyPalette<MyObj> palette = new MyPalette<MyObj>("palette",
myAssociated, myAvailable, getPaletteRenderer(),
25, false) {
};
form.add(palette);
form.add(new AjaxSubmitLink("saveButton") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
......
}
@Override
protected void onError(AjaxRequestTarget target, Form<?> form) {
......
}
});
add(form);
}
Now MyPanel class:
public class MyPanel extends Panel {
(....)
final AutoCompleteTextField<MyObj> autoComplete = new
AutoCompleteTextField<MyObj>(
"code", codeModel, getAutocompleteRenderer()) {
final List<MyObj> codeList = codeListModel.getObject();
@Override
protected Iterator<MyObj> getChoices(String input) {
(...)
return choices.iterator();
}
@Override
public <C extends Object>
org.apache.wicket.util.convert.IConverter<C>
getConverter(java.lang.Class<C> type) {
return new IConverter(){
(....)
}
@Override
public String convertToString(Object value, Locale locale) {
(...)
}
};
}
};
public MyPanel(String id) {
super(id);
autoComplete.add( new AjaxFormComponentUpdatingBehavior(
"onchange") {
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
send(this.getComponent().getPage(), Broadcast.BREADTH,
new AutoCompleteUpdate(target,autoComplete.getConvertedInput()));
}
});
add(autoComplete);
}
}
