[flexcoders] Add New Item to Datagrid

[David C. Moody]

Hi,

I'm having trouble.  I have done this before, and it is actually 
running in a program now.  But for the life of me I can't make it 
work again.

I'm using Alex Harui's method:

tml

Here's my AS code:

private function generateObject():Object {
        return { account: "" }
}
                
private function isObjectEmpty(obj:Object):Boolean {
        return obj.account == "";
        //return obj.employee == "" & obj.reason == "";
}
                
private function gotCheckData(evt:ResultEvent):void {
        var ac:NewEntryArrayCollection = new NewEntryArrayCollection 
(evt.result as Array );
        ac.factoryFunction = generateObject;
        ac.emptyTestFunction = isObjectEmpty;
        ckData.dataProvider = ac;
        //ckData.dataProvider = evt.result;
}

Here's my DataGrid:
<mx:DataGrid x="10" y="245" width="560" height="204" id="ckData" 
editable="true">
        <mx:columns>
                <mx:DataGridColumn headerText="Account" 
dataField="account" width="75" 
itemRenderer="com.coachflex.objects.PlaceHolderItemRenderer"/>
                <mx:DataGridColumn headerText="Description" 
dataField="description" editable="false"/>
                <mx:DataGridColumn headerText="Amount" 
dataField="amount" width="75" />
                <mx:DataGridColumn headerText="Tour #" 
dataField="tour_num" width="75" />
                <mx:DataGridColumn headerText="Use Date" 
dataField="use_date" width="75" />
        </mx:columns>
</mx:DataGrid>


The Datagrid is completely empty.  I can edit the blank rows, but it 
should have data in it.

If I comment out the NewEntryArrayCollection stuff and just have 
ckData.dataProvider = evt.result;

My data shows up.  Why can I not see current data??  This is blowing 
my mind as I have it working in another program.

The recordset has the following columns:
recnum, tour_num, use_date, account, amount, description


Thanks in advance!!
