I'm trying to copy file with SPServices but my file stays 'linked' (if You open details - SharePoint says this is a copy and offers to unlink). I got my new item with another query and tried to
addedItem.set_item("RelatedId", currentId); // just for example addedItem.set_item("_CopySource", ""); // error here addedItem.update();
but get error that "This property is not updatable"
I found that there is no way to unlink using js, is it right? Also - strange that SPServices updates details even if I comment 'Fields' setting at all.. How do You make file copies and update details in JSOM?
Here is part of my code: gist
Also as I google - this CopyIntoItems function is a little strange
