Hi Alex,
Here's a stack trace. When you say 'we' do you mean 'we software
engineers at Adobe'? Who y'all can do something to get 'er fixed up?
captureItemPosition: set myeditedItemPosition r/c=5,12
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

And here is the function with line numbers where the things goes awry:
DataGrid.as
Line#4703: /**
* @private
* focus an item renderer in the grid - harder than it looks
*/
private function
itemEditorItemEditBeginHandler(event:DataGridEvent):void
{
trace ('jgharris put this here');
// weak reference for deactivation
if (stage)
stage.addEventListener(Event.DEACTIVATE,
deactivateHandler, false, 0, true);
// if not prevented and if data is not null (might be from
dataservices)
if (!event.isDefaultPrevented() &&
listItems[actualRowIndex][actualColIndex].data != null)
{
createItemEditor(event.columnIndex, event.rowIndex);
if (editedItemRenderer is IDropInListItemRenderer &&
itemEditorInstance is IDropInListItemRenderer)
IDropInListItemRenderer(itemEditorInstance).listData =
IDropInListItemRenderer(editedItemRenderer).listData;
// if rendererIsEditor, don't apply the data as the data
may have already changed in some way.
// This can happen if clicking on a checkbox
rendererIsEditor as the checkbox will try to change
// its value as we try to stuff in an old value here.
if (!columns[event.columnIndex].rendererIsEditor)
itemEditorInstance.data = editedItemRenderer.data;
if (itemEditorInstance is IInvalidating)
IInvalidating(itemEditorInstance).validateNow();
if (itemEditorInstance is IIMESupport)
IIMESupport(itemEditorInstance).imeMode =
(columns[event.columnIndex].imeMode == null) ?
_imeMode : columns[event.columnIndex].imeMode;
var fm:IFocusManager = focusManager;
// trace("setting focus to item editor");
if (itemEditorInstance is IFocusManagerComponent)
fm.setFocus(IFocusManagerComponent(itemEditorInstance));
fm.defaultButtonEnabled = false;
var event:DataGridEvent =
Line#4741: new DataGridEvent(DataGridEvent.ITEM_FOCUS_IN);
event.columnIndex = _editedItemPosition.columnIndex;
event.rowIndex = _editedItemPosition.rowIndex;
event.itemRenderer = itemEditorInstance;
dispatchEvent(event);
}
}
===================================================
It bonks out at:
Line#4741
var event:DataGridEvent =
new DataGridEvent(DataGridEvent.ITEM_FOCUS_IN);
==============================================================
Hopefully useful to us all.
They say in the real world, 'Money talks and bullsh*t walks.'
They don't say whether it walks away or walks around, though.
I think it's around.
