Examples of org.geomajas.gwt.client.command.GwtCommand

org.geomajas.gwt.client.command.GwtCommand

GWT implementation of an RPC request. On the server-side this request is transformed into a command object that is then executed by a CommandDispatcher instance.
@author Pieter De Graef @since 1.6.0


          public void execute(String value) {
            if (value != null) {
              RefreshConfigurationRequest request = new RefreshConfigurationRequest();
              request.setConfigLocations(value.trim().split("[ \\r\\t\\n,;]+"));
              GwtCommand command = new GwtCommand(RefreshConfigurationRequest.COMMAND);
              command.setCommandRequest(request);
              GwtCommandDispatcher.getInstance().execute(command, new CommandCallback() {

                  RefreshConfigurationResponse r = (RefreshConfigurationResponse) response;
                  String message = "Reloaded applications : ";
