@xiaomengat亚搏在线safeUnfortunately I can't upload my workbench because it is too difficult to strip it of company confidential information,however I have posted a separate question here:https://knowledge.亚搏在线safe.com/questions/91381/exposed-elements-in-neighborfinder-are-forgottenar.html
I am having the same issue as Alex in FME Desktop 2018.1.My workbench contains about a dozen NeighborFinder transformers,but no matter what I do,only a handful of them actually save the attributes that I expose after I save and reopen the workbench.Is it possible that the same bug exists in 2018.1?
