> 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
> Assignee: Mihai Chira
> Attachments: FLEX-34383.patch, _removeSkinnableWithVGroup.fxp
>
>
> *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.
> *Notes*:
> * 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.
> * there are a few potential solutions, of course. I'm leaning toward preventing SkinnableContainer.partRemoved() from clearing the old contentGroup's layout (not sure why it does it; no useful blame info in git), as it doesn't look necessary. Patch attached.
> Error: You are not allowed to change the layout for this class. It is read-only.
