XML data refresh bug when sorted descending in 2.0.1

I'm having an issue with refreshing XML data in the grid while there is a descending sort in place.

In the following example, if you sort by column 0 ascending and click the "changedata" button, everything works correctly.

But, if you start over and sort by column 0 descending, the grid only shows the data for 2 of the rows. The new grid count is correct, but the data is blank for most rows.

This only seems to happen if the number of rows changes.

Anybody know of a work around?

Mike, I'm not really sure ( and wolud preffer that Alex confirm/clarify it )
, but I think it is related to:
/javascript.forum.11480.5/refresh-content-in-grid.html
After a few testing, clearRowModel() seems to do the trick.

function changeData(rows){
obj.clearRowModel();
table.setXML( getDocumentFromString(getXml(rows, "change " + count + " " )) ); 
count += 1; 
obj.setRowCount(table.getCount()); 
obj.refresh(); 
 }

Sorry Mike, that breaks the sort order ( So less sure than before), but if this is the right workaround ??? then, re-sort is needed:
function changeData(){  
var i = obj.getSortColumn(); 
var idir = obj.getSortDirection(i);
obj.clearRowModel();
table.setXML( getDocumentFromString(getXml(6, "change " + count + " " )) ); 
count += 1; 
obj.setRowCount(table.getCount()); 
obj.sort(i, idir);
//obj.refresh(); 
 }

Thanks Carlos. That seems to fix the issue, while preserving the sort order.
