---------------------------------
Labels: easyfix easytest (was: )
> ArrayCollection.itemUpdated does not update the view when filterFunction is
> not null
> ------------------------------------------------------------------------------------
>
> Key: FLEX-23785
> URL: https://issues.apache.org/jira/browse/FLEX-23785
> Project: Apache Flex
> Issue Type: Bug
> Components: Collections
> Affects Versions: Adobe Flex SDK 3.5 (Release)
> Environment: Affected OS(s): Windows
> Affected OS(s): Windows XP
> Browser: Firefox 3.x
> Language Found: English
> Reporter: Adobe JIRA
> Labels: easyfix, easytest
>
> Steps to reproduce:
> 1. create an ArrayCollection with filterFunction function(...z):Boolean {
> return true; }
> 2. bind it to mx:List as dataProvider
> 3. change one of the objects and perform ArrayCollection.itemUpdated
>
> Actual Results:
> The view does not change automatically.
>
> Expected Results:
> The view should change.
>
> Workaround (if any):
> Call ArrayCollection.refresh() after all updates
> Reason:
> If filterFunction was null, this would work.
> Code:
> File
> http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/frameworks/projects/framework/src/mx/collections/ListCollectionView.as
> private function handlePropertyChangeEvents(events:Array):void
> Instruction:
> updateEntry.move =
> updateEntry.move
> || filterFunction
> || !updateInfo.property
> || (sort &&
> sort.propertyAffectsSort(String(updateInfo.property)));
> Before this assignment updateEntry.move == false
> But after updateEntry.move == filterFunction (probably should be still
> Boolean)
> Another instruction:
> if (updateEntry.move)
> {
> moveItemInView(updateEntry.item, updateEntry.item,
> eventItems);
> }
> else
> {
> eventItems.push(updateEntry.item);
> }
> As a result of the previous mistake, the if branch executes.
> It's very likely to be working if the else branch executed instead.
> As a final consequence no event is dispatched at the very end of the function.
> When filterFunction is null, the huge if (95% of the function) does not
> execute and the event at the very end of the function is dispatched.
