I am trying to add a custom 'SkinnableComponent' as a child of NavigationContent.
This results in abrupt behavior of the application (Won't launch at all)
However this worked fine if I replaced my custom SkinnableComponent for a custom Group component.
Is there a restriction for NavigationContent that it can't accept SkinnableComponent as its clid ?
Did I mention the SkinnableComponent is a Spark component !?
Seems like this code sample has a few issues. Do you mean s:NavigatorContent instead of s:NavigationContent? Does your CustomSkinnableComponent have a skinClass set on it?
