ListGrid scrollToColumn and hilites not working

[aarathi]

1.SmartClient Version: v8.3p_2013-01-29/Pro Deployment (built 2013-01-29)
2.IE 8, Firefox

I have a grid built like this:

ListGrid grid = new ListGrid();
                grid.setFields(fields.toArray(new ListGridField[0]));
                grid.setData(records.toArray(new RevenueForecastorGridRecord[0]));
                grid.setWidth(1200);
                grid.setHeight(300);
                grid.setUseAllDataSourceFields(Boolean.TRUE);
                grid.setLoadingDataMessage("Loading Report...");
                grid.setAutoFetchData(false);
                grid.setSelectionType(SelectionStyle.SINGLE);
                grid.setAutoFitData(Autofit.VERTICAL);
                grid.setAutoFitMaxRecords(15);
                grid.setAutoFitFieldWidths(true);
                grid.setAutoFitWidthApproach(AutoFitWidthApproach.BOTH);
                grid.setAlternateRecordStyles(true);
                grid.setEditEvent(ListGridEditEvent.CLICK);
                grid.setLeaveScrollbarGap(false);
                grid.setAutoSaveEdits(false);
                grid.setCanEdit(true);
                grid.setEditByCell(true);
                grid.setGroupStartOpen(GroupStartOpen.ALL);
                grid.setGroupByField("bedroomcount");
                grid.setSortField("bedroomcount");
                grid.setSortDirection(SortDirection.ASCENDING);
                grid.scrollToColumn(scrollColumnIndex);
                // set hilite fields

                final List<String> hiliteFieldNames = new ArrayList<String>();
                for (ListGridField field : fields.subList(0, scrollColumnIndex)) {
                    hiliteFieldNames.add(field.getName());
                }
                Hilite[] hilites = new Hilite[] { new Hilite() {
                    {
                        // setFieldNames(hiliteFieldNames.toArray(new String[0]));
                        setBackgroundColor("#FF00FF");
                        setCssText("background-color:#FF00FF");
                        setId("0");
                    }
                } };
                grid.setHilites(hilites);
                grid.setHiliteProperty("0");

                panel.removeMembers(panel.getMembers());
                panel.addMember(grid);
                panel.redraw();

Neither the scrollToColumn nor the column hilites work. Also in the dev hosted mode I see a bunch of the following warnings listed.

These warnings do not show up when I comment out the scrollToColumn() setting on the grid.Not sure how to get around this issue.

[Isomorphic]

scrollToColumn() can't work while the grid is not yet drawn and doesn't have data (the empty message is showing). Try scrolling when the DataArrived event fires.

[aarathi]

I added a data arrived handler and set the grid.scrollToColumn and hilites within it but that doesnt work either. In fact I dont even see the handler getting called ( didnt hit a breakpoint in hosted mode).
Would the dataArrivedEvent fire when the grid is not based on a datasource and I set the data on the grid directly through the grid.setData(recordArray) method?
BTW, the warnings obviously dont appear now after I moved the grid.scrollToColumn into the dataArrivedHandler callback.

[Isomorphic]

No DataArrived does not fire if data does not "arrive" over a network.

In this case, just move scrollToColumn() to a DrawHandler.
