Listening for view change

[daviesd <da...@oclc.org>]

I¹m working on this user preferences ui.  I have the need to listen for a
view change request.  For example my chrome has a dropdown with all the
views supported by the gadget listed as well as a preferences view added
(even if the gadget doesn¹t support it).  Now I want to know when the
preferences option is chosen.

I tried a couple of things.

1. setup a onNavigated lifecycle listener.  This gets called, but since my
gadget doesn¹t have the preferences view it get a siteHolder.view of
default.  Is there a way to find the originally requested view?
2. I setup a 
container.config_[osapi.container.ContainerConfig.NAVIGATE_CALLBACK] (like
the SET_PREFERENCES, etc.).  I must be missing something here, cuz I don¹t
seem to be getting called.
3. register a requestNavigateTo rpc function.  This gets called, but only
when the gadget is requesting navigation, not my container.

Ideas on my best approach here?

Doug, before you get to far down this path, I am not sure I personally 
agree with a preferences UI implementation being included in a feature.  I 
think containers are going to want to customize it so much that it wont 
end up being useful.  I think something like a Dojo widget or a JQuery 
plugin to do the same thing would be more useful.  This is just my 
thoughts, if others think this is useful, than disregard what I think :)
