Since 1.6 the moveRowUp moveRowDown fuctions don't work

Every time I try I get thid error:



this.getRowById(…)._xml_await’ is null or not an object



Any suggestions?

The problem can’t be reconstructed locally - row moving works as expected.

The error which you mention, can occur when hasChildren method called against not existing row.
