Dg ui does not support multicol sort. I recommend custom dg headerrenderers that will show the columns involved. Our adg is using numbers in the arrows iirc

Ok, I have implemented the multiple column sort (thanks for the help Alex). It works fine, but now the sortArrow disapeared and I can not change the sort direction. I've tried to use the placeSortArrow() function, but this function seems not to exist in the SDK I'm using (Flex 3 Beta 2). Why is that ? Any idea ?
