Hum, I can't see redrawRow on DataGrid. I'm on 2.4 - perhaps it's in a different release?

Ah, yes, it's new in 2.5.0-rc1)

 

My data is exposed through AsyncDataProvider. I'm currently using this monstrosity to update rows, but I'm not entirely confident that it's right or particularly sane.

int i = table.getVisibleItems().indexOf(instance);

if(i >= 0) {

  table.setRowData(table.getPageStart() + i, Arrays.asList(instance));

}

I've been using a similar trick for a CellTree, and I must say I'm not comfortable with it either. But it works, with few reasons to break in a future release (unless some kind of optimization is added to avoid redrawing a row if the object is the same, but it would break a lot of people's code so it has little to no chance to happen in practice)
