RE: Custom SortComparefunction to avoid empty data

[Kessler CTR Mark J]

I'm guessing just test for an empty string / value when doing the compare for 
that column.  Only catch is to watch for the sorting direction to always force 
the blanks down.  Here is a page [1] that may help.  Below is a from the hip 
example I put together... although it needs 


import spark.components.gridClasses.GridColumn;
import spark.globalization.SortingCollator;

protected var collator:SortingCollator = new SortingCollator();


function sortCompareWhatnot(obj1:Object, obj2:Object, gc:GridColumn):int
{
    if (String(obj1[gc.dataField]) == "")
    {
        if (gc.sortDescending == true)
        {
            return -1
        }

        return 1;
    }

    if (String(obj2[gc.dataField]) == "")
    {
        if (gc.sortDescending == true)
        {
            return 1
        }

        return -1;
    }

    return collator.compare(obj1[gc.dataField], obj2[gc.dataField]);
}


<s:GridColumn sortcompareFunction="sortCompareWhatnot" />
