Mihai Chira created FLEX-34383:
----------------------------------
Summary: RTE when removing SkinnableContainer with
skinDestructionPolicy "auto" and SkinnableContainer skin with VGroup or HGroup
as the "contentGroup"
Key: FLEX-34383
URL: https://issues.apache.org/jira/browse/FLEX-34383
Project: Apache Flex
Issue Type: Bug
Components: Spark: SkinnableContainer
Affects Versions: Apache Flex 4.12.1
Reporter: Mihai Chira
*Steps to reproduce*:
# Import and run the attached project.
# Press the button.
*Actual behaviour*: The application throws the RTE below.
*Desired behaviour*: The "container" component is simply removed from stage,
with no RTE.
*Note*: the only change I made to the default SkinnableContainerSkin in
EmptyContainerSkin.mxml is the use of VGroup (or HGroup) as the "contentGroup",
instead of the standard Group.
