UITableView selectRowAtIndexPath does nothing

I am having a problem getting selectRowAtIndexPath to work. If I call the selectRowForIndexPath function before starting an animation, that flips the tableview in question, the tableview will not highlight the tableview row as requested. In fact, it seems that doing anything to the tableview does not give any response. What can be the problem?

I also called setNeedsDisplay and whatnot, but the functions don't seem to be doing anything.

- (void)setCurrentTAType:(MHAbstractTAParameter *)aoTAParameter sequenceNo:(NSInteger)aiSequence {

    m_iSequence = aiSequence;
    NSInteger iSelectedRow = 0;

    if ([aoTAParameter isKindOfClass:[MHOverlayTAParameter class]]) {
        m_iDisplayType = MHChartTADisplayOverlay;
        [m_oTableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];

        MHOverlayTAParameter *oOverlayParam = (MHOverlayTAParameter *)aoTAParameter;

        switch (oOverlayParam.iOverlayTAType) {
            case MHChartOverlayNone:
                iSelectedRow = 0;
                break;
            case MHChartOverlaySMA:
                iSelectedRow = 1;
                break;
            case MHChartOverlayWMA:
                iSelectedRow = 2;
                break;
            case MHChartOverlayEMA:
                iSelectedRow = 3;
                break;
            case MHChartOverlaySAR:
                iSelectedRow = 4;
                break;
            case MHChartOverlayBoll:
                iSelectedRow = 5;
                break;
            default:
                iSelectedRow = 0;
                break;

        MHUnderlayTAParameter *oUnderlayParam = (MHUnderlayTAParameter *)aoTAParameter;

Get rid of

[m_oTableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];

I have a feeling this doesn't complete before you tell the table to select that row and hence the specified index path might not exist.

Simply replace that call with [m_oTableView reloadData] and see if that works
