Updating dataprovider causes mess when scrolling in AdvancedDataGrid

Question

Hi
I have a problem using AdvancedDataGrid :
I bind the ADG dataprovider to a XML in my model, like this :
       <mx:AdvancedDataGrid
            <mx:dataProvider>
                <mx:HierarchicalCollectionView filterFunction="{model.filterFunction}" source="{hierarchicalData}"/>
            </mx:dataProvider>
            <mx:columns>   
                <mx:AdvancedDataGridColumn labelFunction="{model.menuLabel}"/>
             </mx:columns>
       </mx:AdvancedDataGrid>
    <fx:Declarations>
        <mx:HierarchicalData id="hierarchicalData" source="{model.myXML.xmlNode}"/>
    </fx:Declarations>
When I start the application, the ADG displays poperly my model.
Then I programmaticaly add a node to myXML in my model, the ADG renders it and adds a row. So far so good.
Then when I scroll vertically in the ADG, some rows are added or removed, or the mouse highlighting jump to another line... Total mess.
I read that this may be because ADG recycle renderers and so we have to override the "set data" function in renderer. But here I don't use renderer but labelFunction.
And I don't have the problem when scrolling, until I change the dataprovider.
Do you have an idea ?

Answer 1

can you post your source project? you must be addding the node the array collec
tion more then once??? maybe. I wouldnt be able to tell unless you posted your project and we can take a look at it.
