GwtRpcDataSource: WARN:ResultSet:isc_ResultSet_1 (created by:.):get: invalid index -1

[ludi]

Hello,

after updating to SmartGWT 2.1 I received the following error on an empty ListGrid:
RDQ7:WARN:ResultSet:isc_ResultSet_1 (created by: isc_OID_39):get: invalid index -1

As datasource I used the GwtRpcDataSource Version 1.0.

The fetch code looks like:

		@Override
		protected void executeFetch(final String requestId,
				final DSRequest request, final DSResponse response) {
			
			AdministratorService.Util.getInstance().getModerators(customer.getIdCustomer(),	new AsyncCallback<List<User>>() {

						public void onFailure(Throwable caught) {
							response.setStatus(RPCResponse.STATUS_FAILURE);
							processResponse(requestId, response);
						}

						public void onSuccess(List<User> result) {
							//damit wir nicht immer neu laden müssen
							users = result;
							// Calculating size of return list
							int size = result.size();
							
							ListGridRecord[] list = new ListGridRecord[size];
							for (int i = 0; i < result.size(); i++) {
								ListGridRecord record = new ListGridRecord();
								record.setAttribute("name", result.get(i).getName());
								record.setAttribute("active", result.get(i).isActive());
								list[i] = record;
							}
						
							response.setData(list);
							// IMPORTANT: for paging to work we have to specify
							// size of full result set
							response.setTotalRows(result.size());
							processResponse(requestId, response);
							
						}
					});
		}

Does anyone have an idea?
Thanks

Hi,

i am also getting the same error/warning. Is it to be ignored? Or how it is to be fixed?

Thanks

Same Error

I'm also getting this, any fixes?

[mljolje]

Same case at my place.
I thnik it has some connection with
processResponse(requestId, response); and
ListGrid.setFields() method.

No solution for that yet.

same

I get the same warning. Very ugly :-(

get the same error. i used the rpc datasource in a comboboxitem. no items were shown after reply from the server, but the record array is filled. here is my code. can somebody help me please.

final ComboBoxItem productChooser = new ComboBoxItem();
final ProductDataSource productDataSource = new ProductDataSource();
productChooser.setOptionDataSource(productDataSource);
productChooser.setFetchDelay(500);
productChooser.setValueField("productNr");
productChooser.setDisplayField("productDescription");
productChooser.addChangedHandler(new ChangedHandler() {

	@Override
	public void onChanged(final ChangedEvent event) {
		if (event.getValue() != null
				&& event.getValue().toString().length() > 0) {
			Criteria criteria = new Criteria();
			criteria.setAttribute("companyId", Fakturator.instance
					.getCompanyId());
			criteria.setAttribute("text", event.getValue().toString());
			productDataSource.fetchData(criteria, new DSCallback() {
					@Override
				public void execute(DSResponse response,
						Object rawData, DSRequest request) {
					Record[] data = response.getData();
					for (Record record : data) {
						productDataSource.addData(record);
					}
				}
			});
		}
	}
});
positionProductNr.setEditorType(productChooser);

and here my datasource code

public class ProductDataSource extends GwtRpcDataSource<Product> {

	DataSourceIntegerField productId = new DataSourceIntegerField("id");
	DataSourceTextField productNrField = new DataSourceTextField("productNr");
	DataSourceTextField productDescriptionField = new DataSourceTextField(
			"productDesciption");

	/**

	public ProductDataSource() {

		productId.setPrimaryKey(true);
		setFields(productId, productNrField, productDescriptionField);
	}

	/**
	 * {@inheriteDoc}
	 */
	@Override
	protected void executeAdd(String requestId, DSRequest request,
			DSResponse response) {

	}

	/**
	 * {@inheriteDoc}
	 */
	@Override
	protected void executeFetch(final String requestId, DSRequest request,
			final DSResponse response) {
		ProductServiceAsync service = GWT.create(ProductService.class);
		Integer companyId = request.getCriteria()
				.getAttributeAsInt("companyId");
		String text = request.getCriteria().getAttributeAsString("text");
		service.findProductByDescription(companyId, text,
				new AsyncCallback<FetchResult<Product>>() {
					public void onFailure(Throwable caught) {
						response.setStatus(RPCResponse.STATUS_FAILURE);
						processResponse(requestId, response);
					}

					public void onSuccess(FetchResult<Product> result) {
						ProductRecord[] list = new ProductRecord[result
								.getFetchedList().size()];
						for (int i = 0; i < list.length; i++) {
							ProductRecord record = new ProductRecord();
							copyValues(result.getFetchedList().get(i), record);
							list[i] = record;
						}
						response.setData(list);
						response.setStartRow(result.getStartRow());
						response.setEndRow(result.getEndRow());
						response.setTotalRows(result.getTotalRows());
						processResponse(requestId, response);
					}
				});
	}

	@Override

	}

	private static void copyValues(Product from, ProductRecord to) {
		to.setProductId(from.getId());
