Re: [flexcoders] Flex beta 2 - add, remove and moving DataGridColumn

I've noticed that you can't actually manipulate the columns property directly cause it looks like the grid returns a copy of its internal columns array. eg:

   trace(grid.columns == grid.columns);   //outputs "false"

So doing things like "grid.columns.push(...)" doesn't change anything, even if you call invalidateDisplayList().  I've had to assign back the property:

   var cols: Array = grid.columns;
   cols.push (...);
   grid.columns = col;

Once you assign the property, the grid automatically redraws itself.

The columns are stored in an Array.  You simply need to manipulate the array using operations like splice.  Then make sure to call invalidateDisplayList to get it to redraw.
