Hi,I wanted to to tell you that I am not able to re paint the
CellBrowser by ListDataProvider . My code is:
public class CustomTreeModel implements TreeViewModel {
private ArticuloFormularioSeleccionCategoriaUIHandlers iuHandler;
private final SingleSelectionModel<String> selectionModel = new
SingleSelectionModel<String>();
// Mapa de prueba q simula el servicio del server de consulta de
categoria relacionada
public static HashMap<String, ArrayList<String>> categorias = new
HashMap<String, ArrayList<String>>();
/**
* Get the {@link NodeInfo} that provides the children of the
specified value.
*/
@Override
public <T> NodeInfo<?> getNodeInfo(T value) {
String categoriaSelected = value == null ? null : (String)
value;
CategoriaProvider dataProvider = new
CategoriaProvider(iuHandler,
categoriaSelected);
// Return a node info that pairs the data with a cell.
return new DefaultNodeInfo<String>(dataProvider, new TextCell(),
selectionModel, null);
}
public void cargarDatos() {
}
/**
* Check if the specified value represents a leaf node. Leaf nodes
cannot be opened.
*/
public boolean isLeaf(Object value) {
ArrayList<String> subCategorias =
categorias.get(value.toString());
return (subCategorias == null) ? true : false;
}
public String getCategoriaSeleccionada() {
return selectionModel.getSelectedObject();
}
public SingleSelectionModel getSelecctionHandler() {
return this.selectionModel;
}
public ArticuloFormularioSeleccionCategoriaUIHandlers getIuHandler()
{
return iuHandler;
}
public void
setIuHandler(ArticuloFormularioSeleccionCategoriaUIHandlers iuHandler)
{
this.iuHandler = iuHandler;
}
public class CategoriaProvider extends ListDataProvider<String> {
private ArticuloFormularioSeleccionCategoriaUIHandlers
uiHandler;
private String categoriaSeleccionada;
public
CategoriaProvider(ArticuloFormularioSeleccionCategoriaUIHandlers
uiHandler, String categoria) {
super();
this.categoriaSeleccionada = categoria;
this.uiHandler = uiHandler;
}
@Override
protected void onRangeChanged(final HasData<String> display) {
super.onRangeChanged(display);
if (uiHandler == null)
return;
if (categoriaSeleccionada == null) {
uiHandler.getCategoriaDeArticuloClientService().obtenerCategoriasDeArticulos(new
AsyncCallback<ArrayList<CategoriaDeArticuloDto>>() {
@Override
public void
onSuccess(ArrayList<CategoriaDeArticuloDto> result) {
ArrayList<String> categorias =
convertCategoriaDeArticuloDto(result);
List list = getList();
list.addAll(categorias);
updateRowCount(categorias.size(), true);
updateRowData(0, categorias);
refresh();
}
@Override
public void onFailure(Throwable caught)
{
caught.printStackTrace();
// TODO falta log de error
}
});
}
}
}
public ArrayList<String>
convertCategoriaDeArticuloDto(ArrayList<CategoriaDeArticuloDto>
result) {
ArrayList<String> categoriasString = new ArrayList<String>();
if (result == null)
return categoriasString;
for (CategoriaDeArticuloDto dto : result) {
categoriasString.add(dto.nombre);
}
return categoriasString;
}
}
Anyone know why this happens?
Thank you very much!
Jero.
