Hi all,
sorry for spamming this group a bit at the moment, but i am really stuck on
several fronts.
I have a parent presenter which works fine. I stripped it down to a few
lines to make it easier do discuss:
public class ContainerEditorDialogPresenterWidget extends
PresenterWidget<ContainerEditorDialogPresenterWidget.MyView> implements
ContainerEditorDialogUiHandlers {
//Constructor, view interface removed ...
private ContainerDto currentContainerDTO = null;
private SimpleBeanEditorDriver<ContainerDto, ?> driver;
@Override
public void onReveal() {
super.onReveal();
driver.edit(currentContainerDTO); // this will populate your view with
the data from your POJO
}
@Override
protected void onBind() {
super.onBind();
driver = getView().createEditorDriver();
}
@Override
public void updateContainer() {
ContainerDto container = driver.flush();
//Here the groupList is null
eventBus.fireEvent(new ContainerUpdatedEvent(container));
}
}
I guess this is fine. I have a child-editor declared in the view:
@UiField GroupListEditor groupListEditor;
and it looks like this:
public class GroupListEditor extends Composite implements
IsEditor<ListEditor<String, GroupItemEditor>> {
private static StringListEditorUiBinder uiBinder = GWT
.create(StringListEditorUiBinder.class);
interface StringListEditorUiBinder extends
UiBinder<Widget, GroupListEditor> {
}
@UiField
FlowPanel pWidget;
@UiField
PushButton bAdd;
@UiField
FlowPanel pList;
ArrayList<String> backingList = new ArrayList<String>();
private class StringItemEditorSource extends EditorSource<GroupItemEditor> {
@Override
public GroupItemEditor create(final int index) {
GroupItemEditor subEditor = new GroupItemEditor();
pList.insert(subEditor, index);
subEditor
.addDeleteHandler(new EditorDeleteEvent.EditorDeleteHandler() {
public void onEditorDeleteEvent(EditorDeleteEvent event) {
remove(index);
}
});
return subEditor;
}
@Override
public void dispose(GroupItemEditor subEditor) {
subEditor.removeFromParent();
}
@Override
public void setIndex(GroupItemEditor editor, int index) {
pList.insert(editor, index);
}
}
private ListEditor<String, GroupItemEditor> editor = ListEditor
.of(new StringItemEditorSource());
public GroupListEditor() {
initWidget(uiBinder.createAndBindUi(this));
editor.setValue(this.backingList);
}
@UiHandler("bAdd")
void onBAddClick(ClickEvent event) {
Log.debug("Add button clicked");
add();
}
private void add() {
String s = "Stuff";
editor.setValue(this.backingList);
editor.getList().add(s);
}
@Override
public ListEditor<String, GroupItemEditor> asEditor() {
return editor;
}
private void remove(final int index) {
editor.getList().remove(index);
}
}
What i do not understand: How do i associate the backing list with this
sub-editor? Convention says that by calling the Editor groupListEditor, it
edits the groupList property of the ContainerDto. But the backing list is
still empty. Then i tried to assign the backing list with a call to
groutListEditor.asEditor() fromt the parent view, the list does still not
get set.
When i do it in the same method like in the add() above:
editor.setValue(this.backingList);
editor.getList().add(s);
I can add an item and get it displayed in the GUI. But when i flush the
driver in the parent presenter, calling getGroupList() returns null.
What would be the right way to do it?
Thanks you very much!
