All right - you wrote you were using a DataGrid, correct? Then I suppose you
also have a DataSet on the stage bound to that DataGrid. The whole think -
well, concerning updates - is about the DataSet.applyUpdates() method. If your
DataGrid is editable and you want that the changes you make to your data using
the DataGrid are reflected in your data model, you have to use applyUpdates().

I suggest you read Data Tutorials - XUpdate Tutorial: Update the Timesheet
(Flash Professional Only) (p. 18), available at MM's Developer Center as a
..pdf. That should help solving your problem.

hi guys, i have been trying to do this for longggggg time, i hope u guys
can help me.

i have an xml file

let say is something like this to make it easier the real aplication is
a kind of monster.

numbers
----1
----2
----3
letters
----a
----b
----c

ok the numbers, lettes, etc are showing in one datagrid and when you
select one of them in a second datagrid it shows the correspond records
for example:

if i pick "numbers" it shows 1,2,3 in a datagrid

when i change for example "2" for "4" it is now 1,4,3 but!!! when i
change the selected item in the first grid and then comeback to the item
i changed before the changes are not made, and it shows 1,2,3 again
