Subject: [flexcoders] mx.managers::HistoryManager$/save -- null has no
properties
I've been having some issues lately with the HistoryManager object
lately. I'm using some TabNavigators to display different pieces of
information. Some of the tabs have objects inside them that are
created using AS, and they're based on custom components that I've
made.
Sometimes when I try to remove a child from a specific tab, or when
I select a different tab, I get the following error stack...
TypeError: Error #1009: null has no properties.

Any ideas on why I'm getting this error and how I can fix it would
be GREATLY appreciated. I have a demo on Wednesday that I'll be
showing the app I've made. I'd really like to have this issue
resolved by then.
