Alex Harui commented on FLEX-34339:
-----------------------------------
I try not to add just-in-case code to the SDK. Again, folks who have
permanently removed a focused widget from the UI should set focus somewhere, so
code that removes focus runs the risk of overriding where they set the focus
to, and I have concerns about certain operations in the player like changing
child indexes that I think actually do a remove/add under the covers. Some of
our effects may also do remove/add under the covers.
If you want to do the legwork of proving that a change will survive remove/adds
or that none of our effects or player behavior does remove/add under the
cover, I will not object to those changes.
> 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).
