Sorting is not working properly.

Hi all,
Grid sorting is not giving correct output. when we click on column head it reveses its order but not sort it. Is this a known problem?
Does anyone know how to fix it?

Thanks,
Sandesh

Please post an example

Here is the code. following method "printCertified()" recieves bean array from java class. This method first converts bean array into multiD array, then sets images for column 3 and 5 and after that it write grid object on document. I am very new to Active Widgets, I may go wrong at very basic level too. Any type of help will appriciated.

function printCertified(options)
{
var i=0;
    optionList1 = new Array();
    for (var data in options)
     {
list=new Array();
list[0]=options[data].requestId;
list[1]=options[data].externalRef;
list[2]=options[data].statusName;
list[3]=options[data].regFlag;
list[4]=options[data].regLevel;
list[5]=options[data].priorety;
list[6]=options[data].mntFlag;
list[7]=options[data].productLine;
list[8]=options[data].version;
list[9]=options[data].product;
list[10]=options[data].labstract;
list[11]=options[data].owner;
list[12]=options[data].objectiveDate;
list[13]=options[data].modificationDate;
list[14]=options[data].activity;
list[15]=options[data].level1;
list[16]=options[data].customer;
optionList1[i]=list;
i=i+1;
}
    var header=["RequestID", "Num", "Status", "Reg", "Reg Level", "Sevirety", "Mgnt", "Product Line", "Version", "Product", "Abstract", "Owner", "ObjectiveDate", "ModificationDate","Activity","Level1","Customer"];
        

var obj = new AW.Grid.Extended;
        obj.setSize(990,350);
        obj.setHeaderText(header);
        obj.setColumnCount(17);
        obj.setRowCount(i);
        
// enable row selectors
        obj.setSelectorVisible(true);
        obj.setSelectorText(function(i){return this.getRowPosition(i)+1});
        if(i>999)
         obj.setSelectorWidth(40);
        else
            obj.setSelectorWidth(25);
        
// set row selection
        obj.setSelectionMode("single-row");

            //setting image for priorety
        obj.setCellData(function(col, row){return col + "." + row});
        function image(col, row){
if (this.getCellText(5, row) == "1") {
return "p1";
}
else if (this.getCellText(5, row) == "2") {
return "p2";
}
else if (this.getCellText(5, row) == "3") {
return "p3";
}
else if (this.getCellText(5, row) == "4") {
return "p4";
}
}
    obj.setCellTemplate(new AW.Templates.Image, 5);
obj.setCellImage(image, 5);

//setting image for regression
        obj.setCellData(function(col, row){return col + "." + row});
    function imageReg(col, row){
if (this.getCellText(3, row) == "1") {
return "reg";
}
else
return;
}
obj.setCellTemplate(new AW.Templates.Image, 3);
obj.setCellImage(imageReg, 3);

//open case on double click
obj.onCellDoubleClicked = function(event, column, row){
if(column==1)
window.open( 'Case?requestid='+this.getCellText(0,row), '', 'width=300,height=200,top=120,left=120,menubar=1, toolbar=1, resizable=1, scrollbars=1, status=1' );
};

//setting list of cases
    obj.setCellText(optionList1);
    document.write(obj);

If I remove code of images then it is working fine.
Does anyone know how to use images in grid in a way that would not affect sorting of grids?

Thanks,
