Record Select Timing Issue?

$

I'm encountering what appears to be a SGWT timing issue: Whether my record selection gets applied or not appears to depend on the size of the result set.

Given the following code...
Code:

ListGrid listGrid = new ListGrid() {
...
addDataArrivedHandler(new DataArrivedHandler() {
 @Override
 public void onDataArrived(DataArrivedEvent event) {
  selectSingleRecord(3); // simple demo
 }
});

groupBy("SUBGROUP", "APPROVER_NAME");

setSortField("STARTDATETIME");
...

...what I'm seeing is that if the Grouping process takes too long, the record selection is not shown.

When the result set is under ~50 records, the record selection works. When it's over ~50 records, the redraw of the ListGrid to show the Grouping takes longer, and the record does not appear selected at the conclusion.

I tried the GroupByCompleteHandler too. That always works for user-initiated Grouping via header context menu. But it does not work for the initial page load.

Please advise, thanks.
