> ------------------------------------------------------------------------------------
>                 Key: FLEX-34188
>                 URL: https://issues.apache.org/jira/browse/FLEX-34188
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Focus Manager, Tooltip Manager
>    Affects Versions: Apache Flex 4.11.0
>            Reporter: Mihai Chira
>              Labels: easytest
>             Fix For: Apache Flex 4.13.0
>         Attachments: FLEX-34188.patch, _ToolTipManager1009.fxp
> Steps to reproduce:
> 1. Run the attached AIR project
> 2. Move your mouse over one of the item renderers in the second row (and don't move it
for a bit)
> Current behaviour: the RTE below.
> Expected behaviour: a tooltip should appear next to the renderer.
> -this is most likely caused by FLEX-34187.
> -just like in FLEX-34187, we can reproduce this no matter to whom we give focus before
removing the grid.
> -in our application this is causing many similar runtime errors when transitioning from
complex views which contain DataGrids.
> -UIFTETextField (the default renderer) seems to be the only component left whose systemManager
value depends on whether it's on stage or not. If the effects range beyond interfering with
ToolTipManager, maybe we can make it implement a caching method similar to UIComponent?
> RTE:
> TypeError: Error #1009: Cannot access a property or method of a null object reference.
