----------------------------------
Summary: Spark Datagrid inconsistency: hovered column header index
erroneously shown as -1
Key: FLEX-35260
URL: https://issues.apache.org/jira/browse/FLEX-35260
Project: Apache Flex
Issue Type: Bug
Components: Spark: DataGrid
Affects Versions: Apache Flex 4.14.1
Reporter: Mihai Chira
Assignee: Mihai Chira
(To clearly see the inconsistency, run the attached project.)
* The last column of a {{DataGrid}} can be sized to end before the grid ends.
* Although this space between the last column separator and the end of the grid
looks just like the last column header (which in fact it is),
{{GridColumnHeaderGroup.getHeaderIndexAt()}} returns {{-1}}, falsely indicating
that there's no column under the mouse pointer.
* Moreover, the {{GridColumnHeaderGroup}} does not dispatch the
{{GridEvent.GRID_ROLL_OVER}} and {{GridEvent.GRID_ROLL_OUT}} events for that
part of the last header.
