             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.
