Thats exactly what I'm doing. I have a java object mapped to a Flex object.
Here's what they look like:
public class DataVO {
private Object[][] dataValues;
public DataVO(Object[][] dataValues) {
}
}
Since there are no specific attributes, I get 0,1,2... for the column
headers in the Flex DataGrid. However, the headers show up in the
opposite order. i.e. if I was returning 5 columns, I see
Col4 Col3 Col2 Col1 Col0 instead of seeing
Col0 Col1 Col2 Col3 Col4
I got a reply earlier on this forum saying thats just the way AS
evaluates arrays. I'm looking for a clean way to display the data in
the correct order. I don't see a setAt(x,y,Object) or equivalent
method for the DataGrid so I could populate the grid from an AS
function. Is there any way to do this?
Thx for your help on this.
