Hi,
   I am a newbie to DWR. i am trying to populate a drop down box by returning an object array. I am getting a javascript alert saying [object error].

This is my javascript code.
.......
function populateDepartments()
{
    Helper.getAllDepartments(createList);
}

function createList(data)
{
    DWRUtil.removeAllOptions("dept");
    $("dept").options[$("dept").options.length] = new Option(" ");
    DWRUtil.addOptions("dept", data,"costCenterId", "costCenterName");
}
.......


My Java Code

public class Helper {
....
public DepartmentParam[] getAllDepartments()
    {
        List list = role.getAllDepartments();
        DepartmentParam[] depts = (DepartmentParam[]) list.toArray(new DepartmentParam[list.size()]);
        return depts;
    }
....
}

DepartmentParam has two attributes costCenterId and costCenterName.

Where i am making the mistake?

thanks in advance,
