i have to do a bunch of find/replace ops to bring things inline with standards, blah, blah, blah. but the dialog, while telling me it will replace something, doesn't actually replace it. and i wind up having to manually copy/paste 800+ items. this is sub-optimal. 
can a more enlightened soul explain what's happening here? i have a feeling i know the answer and i pre-don't like it. 
It's a bug 
We're leaving the old reference around, but the UI just isn't aware of it:
"config": {
"fallbackDelay": 2.5,
"mode": "indirect",
"references": {
"abc": "{this.custom.key}"
},
"tagPath": "[System]Gateway/Redundancy/{ghi}"
},
Probably not new, just never caught during initial implementation of find & replace for Perspective.
A bug!? In software!? Never heard of such a thing. 
Fair enough. Might be faster to just export the view and use an IDE to rip through it then re-import it...? Thanks for letting me know, regardless. I thought i'd missed a setting or something.
