I have a datagrid with paging functionality. Everything works as long as I scroll somewhat slow. But if I scroll very fast ot better yet select first row and then press end it crashes. The error is coming out of the following code:
public function setItemAt(item:Object, index:int):Object
if (index < 0 || index >= length)
var message:String = resourceManager.getString(
"collections", "outOfBounds", [ index ]);
throw new RangeError(message);
which is an SDK code.
I can manage to not to get an error but then I see that a hlaf on the grids has blank rows.
Any idea what to do?
Here is my code:
public function handleCreatePendingItemFunction(index:int, ipe:ItemPendingError):Object
numItemsToFetch = pageSize;
var page:uint=Math.floor(index / pageSize);
if (fetchedPages[page] == undefined)
startIndex=pageSize * page;
var endIndex:uint=startIndex + pageSize - 1;
if (endIndex > list.length)
numItemsToFetch=list.length - startIndex;
var request:PagedDataRequest = new PagedDataRequestFactory().getPagedDataRequest(startIndex, numItemsToFetch, null, null, request);
What happens is when a user is scrolling very fast this code gets executed for more than one page. As a result startIndex is not correct and the grid has blank rows.
