Alex Harui commented on FLEX-34339:
-----------------------------------
I think testing index change is probably sufficient. Really, the focused
object shouldn't be going through a bunch of display list changes. Another
change is re-parenting. That can happen when you pop a UI widget to the front
and I think that also does a remove/add.
For sure, you are not the first person to complain about this SDK behavior.
I've just been too chicken to try to take the time to work on it when I think
eventually, you'll change your app to set focus some place anyway. But if this
is something you want to work on, go for it. That's the Apache Way.
> Components don't focusOut when removed from stage
> -------------------------------------------------
>
> Key: FLEX-34339
> URL: https://issues.apache.org/jira/browse/FLEX-34339
> Project: Apache Flex
> Issue Type: Bug
> Components: .Unspecified - Framework
> Affects Versions: Apache Flex 4.12.0
> Reporter: Mihai Chira
> Labels: easytest
> Fix For: Apache Flex 4.13.0
>
> Attachments: _focusOutNotDispatchedOnRemove.fxp
>
>
> *Steps to reproduce*:
> 1. Import and run attached project.
> 2. Click on numeric stepper and then on button. Notice that focusIn and
> focusOut events are dispatched by numeric stepper as expected.
> 3. Shift+Click on the numeric stepper (this will remove it from stage in
> 600ms).
> *Actual behaviour*: focusOut is not dispatched by numeric stepper when it's
> removed from stage.
> *Desired behaviour*: I expect that a focused component should be de-focused
> when removed from stage.
> *NOTES*:
> -This causes at least one other bug: FLEX-34340.
> -Not sure if this is a flash player bug or SDK bug. Or it could be a feature,
> but definitely not an intuitive one.
> -I have a feeling this is related to FLEX-20416 (couldn't check, since the
> attachment is not on the ticket).
