-------------------------------------

             Summary: FocusOut in datagrid causes RTE if target.parent is n=
ull
                 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: Jo=C3=A3o Fernandes


during focusOutHandler, there is a condition that access target.parent.pare=
nt without checking if target.parent is null or not.
There is a quick fix by inverting the 2 last conditions so at line 5017 ins=
tead of having

if (target is IListItemRenderer && target.parent.parent =3D=3D this && targ=
et.parent is ListBaseContentHolder)

we should have

if (target is IListItemRenderer && target.parent is ListBaseContentHolder &=
& target.parent.parent =3D=3D this)

this way, it will never throw an RTE because if target.parent is null, it w=
ill never evaluate the last portion.
