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

[patrickfkellogg]

I have a DataGrid that has dynamic columns (see below).  when i set
the DataGrid's variableRowHeight="true" and wordWrap="true" it resizes
tall and wraps just fine when a cell's contents are really long.

The problem is the next time the DataGrid appears when there is no
data to display it doesn't resize the row height to a normal row
height.  It remains at the previous really tall height.

The fix typically for this is to set the wordWrap="true" in the
DataGridColumn tag and not in the DataGrid tag, but since i am
generating the columns dynamically, I can't do this.  Any one seen
this?  any fix?
thanks. pat kellogg
