I have a DataGrid where one of the columns is a TextArea
control as the itemEditor.
When I edit a cell in the column with the TextArea editor,
the TextArea opens up to a height equivalent to
three rows of data in the grid. The editor works fine; in
fact it's been working this way for some time.
But recently, we enabled horizontal and vertical grid lines
on the grid. When the TextArea editor opens up,
the datagrid horizontal grid lines are drawn across the top
of the control.
I've verified that the TextArea control is not inheriting the
styles related to grid lines
I've verified that the TextArea backgroundAlpha is 1; i.e.
the text on the rows underneath the editor is not
So as near as I can tell, the grid is drawing the gridlines
on top of the editor. I've managed to reproduce this by changing a
in a trivial, flex-only example I found on the web.
Curiously, I also have a PopUpButton editor type - it does
not have grid lines drawn across when the dropdown
area that appears when the button is activated.
