Hi all,
Any ideas why on scroll of a datagrid the #1010 error is firing from
the ListBase class on this line of code: rowMap[r.name].rowIndex =
newIndex;
I have seen this problem in the past with Flex 2 and funnily enough
have not seen it since, now its rearing its head again. Using the
below code (love the comments by the Adobe team) and digging in the
debugger I see that r.name (CustomGridRenderer3134) is not showing
in list of items on the rowMap hence the error being thrown?
protected function shiftRow(oldIndex:int, newIndex:int, numCols:int,
shiftItems:Boolean):void
{
var r:IListItemRenderer;
for (var j:int = 0; j < numCols; j++)
{
r = listItems[oldIndex][j];
if (shiftItems)
{
listItems[newIndex][j] = r;
rowMap[r.name].rowIndex = newIndex;
}
// this is sort of a hack to accomodate the fact that
// scrolling down does a splice which throws off these values.
// probably better to call shiftRow with different parameters?
else
rowMap[r.name].rowIndex = oldIndex;
}
if (shiftItems)
rowInfo[newIndex] = rowInfo[oldIndex];
}
Cheers, Simon
