\"putlistitems/id/replace , behaves like putlistitems/id
Used in creating things like tree display columns. Allows the programmer to easily specify the column order from data or similar and have the list which is the display populated in one pass. Currently, one has to use putlisitems/id and then go through the list pulling the $valuepart of each item and building another list.
It makes populating tree widgets with runtime defined columns much simpler.
