Cannot read property 'document' of null error when Gauge is displayed a second time

[GoogleCodeExporter]

Found in Release:
gwt-visualization-1.1.1

Platform information (OS, Browser, GWT version).  Does the issue exist on
other platforms?
Mac OS + Chrome

I can successfully display a gauge the first time the page is loaded but when I 
try to create a new gauge without reloading the html page (by simply invoking a 
onValueChange() using GWT History), an error (Cannot read property 'document' 
of null error) is thrown

Here's the code:

                                            DataTable data = DataTable.create();
                                            data.addColumn(ColumnType.STRING, "Task");
                                            data.addColumn(ColumnType.NUMBER, "Hours per Day");

                                            data.addRows(1);
                                            data.setValue(0, 0, "Response");

                                            data.setValue(0, 1, 1);
                                            gauge = new Gauge(data, createOptions());;
                                            gauge.setStyleName("gauge");
                                            gauge.setWidth("200px");

                                            panelResults.add(gauge);

Of course this is called after    
VisualizationUtils.loadVisualizationApi(onLoadCallback, Gauge.PACKAGE);

Workaround if you have one:
None
