For the moment I have only two tasks on three. This of the second
project (out of three) isn't here.
here is the code :
private function getTasks():void
{
currentState='';
if (document.listProject.selectedIndex == -1)
{
tasksArray = new ArrayCollection();
var projectsArray:ArrayCollection =
ArrayCollection(document.listProject.dataProvider);
var tmpArray:ArrayCollection = new ArrayCollection();
var i:int;
for (i = 0; i < projectsArray.length; i++)
{
tmpArray.addEventListener(CollectionEvent.COLLECTION_CHANGE,
collectionChangeHandler);
taskDataService.fill(tmpArray, "tasksProject",
[projectsArray.getItemAt(i).id]);
}
}
else
taskDataService.fill(document.tasksArray, "tasksProject",
[document.listProject.selectedItem.id]);
}
private function collectionChangeHandler(event:CollectionEvent):void
{
if (event.kind == CollectionEventKind.RESET)
{
// display the length using the event.target.length
var tmpArray:ArrayCollection = ArrayCollection(event.target);
var j:int;
for (j = 0; j < tmpArray.length; j++)
document.tasksArray.addItem(tmpArray.getItemAt(j));
}
}
