Re: [flexcoders] Re: FadeIn Effect not working with custom item renderers in List
I have to add, itemsChangeEffect works fine on tileList using itemrenderers (with containers) the problem is strictly related to the itemsChangeEffect addItem effects behaviour on a List only. the effect is playing fine on the removeItem.

Amy,
I have tried that but it still does not display properly. I've tried
changing the Canvas component to other container objects, but they all
appear to exhibit the same functionality.
I've tried with both 3.1 and 3.2 versions of the SDK.
The list effect starts with a background color of blue (to make it
easier to see what's happening). When using just a Label as the
renderer, I can see the blue background boxes resizing into position
and then the label fading into view over the 4 second duration.
But when using any sort of container object (admittedly I've only
tried Canvas, HBox and VBox), the list remains white for the entire 4
second duration, at which point, the renderers become visible
immediately (with no blue background or fading at all).
When I place both list views on the screen at once, they both exhibit
the behaviour of the container renderer. This leads me to believe that
the container is doing something different and the single-threaded
nature of Flash is causing both views to update once the fade effect
has finished.
Problem is, I can't work out what it's doing.

Perhaps I should have been clearer in my original description. The
issue seems to be related to the use of containers as custom
renderers. While I admit that in this case, removal of the container
solves the issue, this is just a simple case to demonstrate the issue.
In my real life case, my item renderers are much more complicated,
containing many sub-components, hence the use of containers.

Problem is, I can't work out what it's doing.
I suspect that the problem is with one of two things:
1) The specific way that the itemsChangeEffect is implemented
2) The loop where you add the items to the ArrayCollection.
The reason I say the first is that you can see an example here
http://flexdiary.blogspot.com/2008/09/groupingcollection-example-
featuring.html where fade effects are working fine on containers. So
if there is a problem with fade effects, it's specific to what
happens in that particular situation.
If it's the second, you can figure it out pretty quickly by calling
disableAutoUpdate() before the loop where you populate the AC and
enableAutoUpdate() after the loop.
Finally, you may want to double-check to make sure that you did
actually set the blendMode on the label to layer.
