Actually, if the default GridItemEditor is used, the RTE will be thrown even
for simple dataField values. See FLEX-34838.
was (Author: evolverine):
Actually, if the default GridItemEditor is used, the RTE will be thrown even
for simple dataField values because in GridItemEditor.save() the sort is
removed from the dataProvider, the change is made, and after that the sort is
reapplied, but without calling refresh() on the collection. This effectively
means that we're fooling the dataProvider into thinking that its items are
correctly sorted according to the sort properties (by this I mean that if we
call getItemIndex, it will use its sort info to find it, thinking everything is
in order), when in fact the order is now practically random. Yes, this can be a
problem when trying to remove the selected item, but it's much wider than that:
keep in mind that usually a dataProvider is accessed by the developers long
after it's assigned to a DataGrid, and they expect (especially if it wasn't
sorted to begin with) that getItemIndex() will work correctly for their custom
code. But due to this bug it doesn't.
