I experienced this when checking a CheckBox itemRenderer inside a DataGrid a few motnhs back. I thought I had determined that it was a change in the underlying dataProvider that caused the problem, but if you're experiencing it just selecting an entire list item that sounds different (but obviously related). I did have some trouble reproducing this bug consistently.
I reported this to our support contact at Adobe but last I heard the engineers were unable to reproduce it. He suspected it might be a bug that was introduced in 2.0.1. Is that the version you're using? There is a fairly painless workaround. In my case, just before updating the item in the dataProvider, I would set the filterFunction to null, then update the value, then reassign the filterFunction. You don't need to call refresh() (I am assuming your dp is an ArrayCollection), so the list won't unsort and resort or anything like that. Sample code below: var ff:Function = myAC.filterFunction; myAC.filterFunction = null; myAC.getItemAt(someIndex).someValue = newValue; myAC.filterFunction = ff; HTH, Ben --- In [email protected], Frank Sommers <[EMAIL PROTECTED]> wrote: > > I have a List, and when a filter function is assigned to that list, > whenever a selection is made (by clicking on a list item), the list > items re-arrange in a strange way.
