If I right click on a symbol instance, I get a menu item, "Break link to symbol." How can I do that same thing in Javascript?
1) That is, how do I use Javascript to break the link between a SymbolItem and the Symbol it represents? (i.e. without deleting the Symbol?)
2) Once the link is broken, how do I locate the Layer that was created when the link was broken? That is, once the link is broken, it is no longer a SymbolItem; it becomes a Layer instead. How do I locate that Layer?
3) How do I convert the Layer to a GroupItem?
