RE: [flexcoders] Re: HistoryManger state is undefined on loading

In looking at the code it looks like anything that isn’t an object will be returned as a string.  All strings turn themselves to true when examined as a Boolean so you may need to do string comparison instead.  Sorry, not much more help than that since I don’t know that code very well.
