I've got a similar issue and I thought I'd piggyback on this thread since I can't get your suggestions to work.
Here's what I've got in my file -
stage / fullRadial symbol / smRadial symbol / gold_btn element
When you click gold_btn I want to hide a different symbol inside of fullRadial call measuringContent. This is the latest code I've tried within the gold_btn element -
On click:
sym.getComposition().getStage().getSymbol("fullRadial").play("Gold Corner");
sym.getComposition().getStage().getSymbol("fullRadial").getSymbol("measuringContent").hide ();
It plays my Gold Corner label just fine, but I've I can't get the hide to work with anything I've tried.
Thanks for any help you can give.
