             Summary: Datagrid goes blank when assigning new dataProvider.source and calling refresh
                 Key: FLEX-33813
                 URL: https://issues.apache.org/jira/browse/FLEX-33813
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: DataGrid
    Affects Versions: Apache Flex 4.10.0
         Environment: OS X, Apache Flex 4.10.0
            Reporter: Gareth Daniel Smith


Given a spark DataGrid with an ArrayCollection dataProvider, the DataGrid can erroneously go blank in the following situation:

- the DataGrid has been scrolled down so it is not at the very top.
- the .source property is changed on the dataProvider to be a new Array where the new values in the Array are also different objects to the objects in the previous .source Array.
- .refresh() is called on the DataGrid

This is possibly the same bug as FLEX-33066.

I will attach a minimal test case.
