> FocusOut in datagrid causes RTE if target.parent is null
> --------------------------------------------------------
>
> Key: FLEX-33263
> URL: https://issues.apache.org/jira/browse/FLEX-33263
> Project: Apache Flex
> Issue Type: Bug
> Components: mx: DataGrid
> Affects Versions: Apache Flex 4.8 (parity release)
> Reporter: João Fernandes
> Assignee: Carol Frampton
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> during focusOutHandler, there is a condition that access target.parent.parent
> without checking if target.parent is null or not.
> There is a quick fix by inverting the 2 last conditions so at line 5017
> instead of having
> if (target is IListItemRenderer && target.parent.parent == this &&
> target.parent is ListBaseContentHolder)
> we should have
> if (target is IListItemRenderer && target.parent is ListBaseContentHolder &&
> target.parent.parent == this)
> this way, it will never throw an RTE because if target.parent is null, it
> will never evaluate the last portion.
