[flexcoders] DataGrid - variableRowHeight="true" and wordWrap="true" not resizing properly

[patrickfkellogg]

I have a problem with <DataGrid> that uses dynamically generated
columns.  When the cell has many characters the row resizes its height
properly with word wrap to show all the cell's contents.  But the next
time the <DataGrid> is shown when there is no data the row height
remains at the previous tall size.  It doesn't resize back down.  I
remember the fix for this before was to place the wordWrap="true" in
the <DataGridColumn> tag not in the <DataGrid> tag, but this is not an
option since I am creating my columns dynamically.  anyone seen this?
 Any fix?  thanks.

 <mx:DataGrid
        id="datagrid"
        width="100%"
        height="100%"
        dataProvider="{report}"
        variableRowHeight="true"
        wordWrap="true"
       
columns="{DataGridColumnFactory.fromColumnGroupVOCollection(report.columns,
model.session.timezoneInfo)}" />
