Mihai Chira updated FLEX-34383:
-------------------------------
Description:
*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.
Error: You are not allowed to change the layout for this class. It is
read-only.
