make selected object visible or invisible in outliner
 

hi,

i met a file that contain some object(group,joint and curve) that invisible in outliner but the object is able to find through node editor or hypergraph.. i had checked on ignore "Hidden in Outliner", checked the shapeNode's "visibility" and "LOD visibility", and also the viewport, but it still invisible in outliner. I have attached a screenshot along with this post, do anyone have any idea on this? Your help is much appreciated, thank you
