[flexcoders] Re: Filterfunction on a XMLListCollection is misbehaving

Here is the relevant code...Without the filter function all edits are
inplace without the updated record gets resorted... thanks.

mx:Script
![CDATA[
.



private function itemFilter (item : Object ) : Boolean
{
return true;
}
]]
/mx:Script



mx:HTTPService id=xmlItems result=searchComplete(event)
resultFormat=e4x contentType=application/x-www-form-urlencoded
fault=httpsFault(event) useProxy=false method=POST
url=items.asp/
mx:XMLListCollection id=xlcItems source={xmlItems.lastResult.item}
filterFunction=itemFilter/
mx:DataGrid sortableColumns=false dataProvider={xlcItems}
id=dgItems headerShift=reGroup(event)
headerRelease=headerRelease(event) editable=false focusAlpha=0.0
doubleClickEnabled=true doubleClick=editItem()
headerStyleName=header headerColors=[#ff,#dd] height=22
fontSize=11 left=10 right=10 top=10 alpha=1.0 bottom=10
borderStyle=solid borderColor=#bb
.
/mx:DataGrid

the
  selectedItem, e.g.
 
  myGrid.selectedItem.dataField = newValue;
 
  This works fine, if I have no filterFunction defined for the
  XMLListCollection. The updates happen inplace, the Grid is updated
and
  the selectedItem (=row) is still highlighted, i.e. selected.
 
  The moment, I specify a filterFunction (one that returns true for
all
  records, mind you), any update to a field in the current
selectedItem
  will resort the Grid (no sort object specified, and the dataGrid
column
  sort is set to false), and the item is always sorted second last in
the
  grid. At the same time the selectedItem property is lost (set to
null).
 
  I know how to disable and enableAutoUpdate (to avoid loosing the
  selectedItem), but it still does not explain, why the grid data gets
  resorted
 
  Any insight from the pros?
 
  Thanks

Correction: WITHOUT the filter function all edits are inplace, WITH the
filter function the updated record gets resorted...
