[flexcoders] Cursor Error: Bookmark no longer valid.

[rleuthold]

Hi,

I'm using a ComboBox with an ArrayCollection as dataProvider.

This ArrayCollection is the source of an AdvancedDataGrid GroupingCollection.

If the users clicks on an item in the ComboBox,the ArrayCollection gets 
filtered:

private function filterNodesInGrid():void
{
        // assign filter function to the AdvancedDataGrid's dataProvider
        IHierarchicalCollectionView(nodes.dataProvider).filterFunction = 
filterByRfids;
        
    // refresh the ADG's dataProvider
    //found in the archives http://www.mail-
archive.com/flexcoders@yahoogroups.com/msg95231.html   
    nodes.invalidateProperties();
 
  IHierarchicalCollectionView(nodes.dataProvider).refresh();
        
  // expand all nodes
    nodes.expandAll();
}


When the refresh is called, this error is thrown: 
        
Bookmark no longer valid.

ListCollectionViewCursor/seek()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\coll
ections\ListCollectionView.as:2046]


... but beside the error, it works correct !? 

Does anybody have an idea how to overcome this issue. 

thank's
