DATAPROVIDER LENGTH - PLEASE HELP

[gevgelija50]

I am not sure if this is a Flex bug or just the wrong approach.

I have two datagrids that have drag-drop enabled. I followed the drag 
and drop example from Macromedia (Flex Explorer)

When I hit the doDragDrop function, instead of simply adding the 
items to the grid, I also want to add them to a global array named 
TestArray.

I assign the items to the array and I can browse the contents of the 
array during my debugging process. However, the length of the array 
and the length of the datagrid dataProvider is set to 0! Althought 
there are items inside the grid.

Why does this happen? Is it because the array is un-accessible in the 
scope of the event?

PLEASE HELP

DATAPROVIDER LENGTH

[gevgelija50]

I have two grids(source and destination) and I am using drag-and-
drop to populate the destination grid.

I have this working and items are moved (sort-of) over to the 
grid. During debugging, I browsed to see the items available in the 
dataProvider for the grid. Items are there but the length of the 
dataProvider is = 0 ??


So, destinationgrid.dataProvider has the following items:


+0 with subfields
+1 with subfields
+2 with subfields

Length should be 3. It shows 0. Any ideas?

Here is my dragdrop function
==
function doDragDrop(event) {

var match_count:Number = 0;
doDragExit(event);

var items = event.dragSource.dataForFormat(items);
var destination = event.target
var exist_items = destination.items;
var dropLoc = dest.getDropLocation()

items.reverse()

for(var i = 0; i  items.length; i++) { 

destination.addItemAt(dropLoc, items[i]); 

}

}

if the length is 0 then it won't show any items. can you post some 
sample code to demonstrate the problem? are you querying the property 
of the grid's dataprovider directly using myDataGrid.dataProvider.length?
