Hello,

In our application we are using a search (autosuggest) combobox with pagination for the results. The extended class is the following:

Code:
public class AjaxPagingComboBox<T extends ModelData> extends ComboBox<T> {    
public interface GetPagingDataCallback<T> {
        void getData(String query, PagingLoadConfig loadConfig,
                AsyncCallback<PagingLoadResult<T>> dataCallback);
    }


    public AjaxPagingComboBox(final String displayField, final int minChars,
            final GetPagingDataCallback<T> getDataCallback) {


        final RpcProxy<PagingLoadResult<T>> proxy = new RpcProxy<PagingLoadResult<T>>() {


            @Override
            protected void load(Object loadConfig,
                    final AsyncCallback<PagingLoadResult<T>> callback) {
                final Map<String, Object> properties = ((PagingLoadConfig) loadConfig)
                        .getProperties();
                getDataCallback.getData((String) properties.get("query"),
                        ((PagingLoadConfig) loadConfig),
                        new AsyncCallback<PagingLoadResult<T>>() {
                            @Override
                            public void onSuccess(
                                    final PagingLoadResult<T> result) {
                                callback.onSuccess(result);
                            }


                            @Override
                            public void onFailure(Throwable caught) {
                                callback.onFailure(caught);


                            }
                        });
            }


        };


        ModelReader reader = new ModelReader();
        final BasePagingLoader<PagingLoadResult<T>> loader = new BasePagingLoader<PagingLoadResult<T>>(
                proxy, reader);
        loader.addListener(Loader.BeforeLoad, new Listener<LoadEvent>() {
            public void handleEvent(LoadEvent be) {
                be.<ModelData> getConfig().set("start",
                        be.<ModelData> getConfig().get("offset"));
            }
        });


        setFieldLabel(displayField);
        final ListStore<T> store = new ListStore<T>(loader);
        setStore(store);
        setHideTrigger(true);
        setMinChars(minChars);
        setUseQueryCache(false);
        setPageSize(10);
    }
However, if the user wants to copy and paste the current value entered in the combo and this field loses focus, a new search is triggered. We would like to disable this behaviour because of some validations we have on the field.

In conclusion, how can I disable a new search when someone uses CTRL + C on the field?

Thank you in advance
