moveItem() triggers errors

dtmlxTree.moveItem() triggers errors:



Uncaught TypeError: Object # has no method ‘_getPrevNode’





I saw another support ticket that says Tree movement is not supported in the standard edition, yet in the documentation it does not say that dhtmlxTree.moveItem() is a professional-only function. How does it work without other professional functions?



Thanks.

Tree movement is not supported in the standard edition
drag-and-drop and moveItem both can be used in standard version, but only as drag-as-child and move-as-child ( moveItem in “item_child” mode )
Support of all moveItem modes and different d-n-d behaviors available only in pro version
