How to save last group field (GroupingView) after refresh browser page?

Hi all!
The grouping column is hidden, if you refresh browser page then group rows is reset, but the grouping column will be hidden. Please, i need help.

Before refresh:
31284

After refresh:
31283

Example: http://www.sencha.com/examples/#grouping
You deleted row for "store.groupBy("industry");" and you will see this trouble ^

I did the following:
override methods (GroupingView):



private void onGroupByClick(MenuEvent me, int colIndex) {
groupingStore.groupBy(cm.getDataIndex(colIndex));
grid.getState().put("lastGroupField", getGroupField()); // write to grid state
}




@Override
protected String renderRows(int startRow, int endRow) {
String groupField = getGroupField();
boolean eg = groupField != null;
if (!showGroupedColumn) {
...
grid.getState().put("lastGroupField", groupField); // write to grid state
}
return super.renderRows(startRow, endRow);
}


and add to grid listener:



grid.addListener(Events.Attach, new Listener<GridEvent<Post>>() {

@Override
public void handleEvent(GridEvent<Post> be) {
...
Map<String, Object> state = grid.getState();
...
if (state.containsKey("lastGroupField")) {
store.groupBy((String) grid.getState().get("lastGroupField"));
}
loader.load(config);
}
});


How it is right? I don't know :)
