Thanks.

The upcomming releaze will eleminate this - also we have changed the concept - The new grouping  will be available next week.

Regards

we have 

grp.sortitems[0].sort();

grp.sortnames[0].sort();

however sortitems don't contain any space, which sortnames do.

then the result will be weird, on the ui the row will be in the wrong group.

I the code in my project to 

grp.sortitems[0].sort();

grp.sortnames[0].sort(

function compare(a,b) 

  {   

var str1 = a.toString().replace(/\s/g, "");

var str2 = b.toString().replace(/\s/g, "");

if (str1 < str2)                                        

  return -1;                                        

 if (str1 > str2)                                     

    return 1;                                       

 return 0;  });

and works fine.
