Calling addItem() on the dataGrid is
actually calling it on the dataProvider and physically adding the line. Now, that line is empty, the “item”
would be undefined (null?), and NOTE THIS: editing a datagrid cell does not
automatically update the datagrid. You will need to use the editCell
event to call editField() to update the dp with the entered data. I bet
your dataProvider has a line but it is empty. Tracy From: Hi,
I would like to extend the scope of this thread by asking How to make this
newly added row as a part of the dataprovider? What I mean is I am able to
create a new row in datagrid by using your methodology. But when I try to
access data in my POJO, I am getting nullpointer exception. That means, I
think, the newly added row to grid is not truly added to dataprovider. Do I
have to make any specific function call to make the newly added row attach to
dataprovider? If this question is already discussed, please guide me with
reference. Thanks! -----Original Message----- Here's a little mod that automatically adds the new
row when you tab out of the last cell. The doLater reminder solved an
aggravating problem I was having! <?xml version="1.0"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml" xmlns="*"> <mx:Script><![CDATA[ function checkOnNav(oEvent:Object):Void { var iItemIndex:Number; var
