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);
callService();
fetchedPages[page]=true;
}
return null;
}
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.
