Hi All,
I am attempting to upgrade a flex app to the 4.10 sdk but i'm
encountering an issue with the spark DataGrid.
My datagrid is displaying as if it has no data (a single column with an
empty header) but it does have horizontal and vertical scrollbars which
seem to be correctly sized for the number of rows/columns that should be
being displayed.
The only 'special' feature of the datagrid is that columns are defined
and added at runtime, rather than via mxml. Debugging shows that
dataProvider property contains the correct ArrayCollection data and the
columns property contains the correct ArrayList (everything worked fine
in 4.9.1).
A quick browse thru the DataGrid change history doesnt alert me to any
changes that could be causing this. Does anybody have any ideas before i
dig deeper?
fyi, scrolling vertically causes this RTE:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

On this line:
ghl.centerGridColumnHeaderView.horizontalScrollPosition =
Number(pce.newValue);
(centerGridColumnHeaderView is null)
