I have a server-side sort on my DataGrid which means I had to implement my own headerRenderer to handle the click event, sort, and server calls.
I am trying to create the asc/desc arrow now but I realized that any click event on the DataGrid instantiates a new Object of the headerRenderer (all of them actually). In other words, my headerRenderer mxml implementation, the creationComplete event gets called any time ANYTHING is clicked in the grid, including a row. This is a problem for many reasons, but the most significant one being that I cannot store the state if the column is ascending/descending based on the user's click. I could store this externally in the model but that is very bad b/c then I'd also have to store which column was clicked and then the other columns have to check if it is itself and remove the arrow if they have one. Does anyone know why the headerRenderer is re-creating an instance of itself every time or faced this issue? Thanks in advance.
