Over ridding the default header names in DataGrid
In the Spark Data Grid, how can I over ride the generated column header
names (assuming my dataProvider is an array of Object) ?
I had a look in the source, but couldn't see where this is assigned to
the labelDisplay skin part ?

The spark datagrid has a columns property which is an IList
(ArrayCollection i think) of DataGridColumn objects - each
DataGridColumn has a headerText property which you can set

The default looks at the object and makes a column per property on the
first row of your IListCollection. Which is good and bad. It is good if you
data is well structured. But if you have new properties beyond the first
row then they aren't given columns.
I've had many clients need the "super dynamic well laid out" datagrid and
in the end I made it where the middle tier sends the data and some
information about how the columns should be created. That way they could do
things like dynamic coloring, aligning, human-readable labels, hidden
columns, etc etc etc. You get the idea.
Depending on how dynamic you need to be you may end up with a similar
solution. Ultimately I created a VO that basically matched all the options
for the datagrid column and the middle tier completely drove the datagrid.

Do you mean like just the headerText of the gridColumns?
<s:DataGrid>
<s:columns>
<s:ArrayList>
<s:GridColumn dataField="VeryLongIDName" headerText="ID" />
<s:GridColumn dataField="EmailAddress" headerText="Email" />
</s:ArrayList>
</s:columns>
</s:DataGrid>
