sort ascend and descend inconsistent?

[acarur01]

Run the following testcase and sort by continent ascending. When sorted ascending, a row with continent = null is the very first on the list. Now sort by continent descending. At this point I would expect the continent = null to be the last row but instead continent = "" is the last row. Is this intended behaviour?

isc.ListGrid.create({
    ID: "countryList",
    width:500, height:224, alternateRecordStyles:true,
    data: countryData,
    fields:[
{name:"continent"},
        {name:"countryCode", title:"Flag", width:50, type:"image", imageURLPrefix:"flags/16/", imageURLSuffix:".png"},
        {name:"countryName", title:"Country"},
        {name:"population", title:"Population", formatCellValue:"isc.Format.toUSString(value)"},
        {name:"area", title:"Area (km²)", formatCellValue:"isc.Format.toUSString(value)"}
    ],
    // initial sort on Population, high-to-low
    sortFieldNum: 2,
    sortDirection: "descending"
})

countryData = [

{
    continent:null,
    countryName:"United States",
    countryCode:"US",
    area:9631420,
    population:298444215,
    gdp:12360.0,
    independence:new Date(1776,6,4),

    government_desc:2,

},
{
    continent:"",
    countryName:"China",
    countryCode:"CH",

One of our Engineers is assigned to take a look, we'll let you know as soon as we have more information

The case you mention should be working now in SC 8.3d/SGWT 3.1d; the next nightly will have it.

I forget to mention each time because I assume everyone working in SC knows (sorry)- we are still working with 8.2p

The fix has been ported to SC 8.2d/SGWT 3.0d.
