Mapstraction - Jan 2010 - "API ID not available" error in toProprietary()

Hi all,

An exception is bubbling up to core whenever the toProprietary()  
function is called. This appears to happen in all providers.

To see it in action, add this line...
var yahoopt = mapstraction.getCenter().toProprietary();

... at the bottom of the initialize function in the Sandbox:
http://mapstraction.appspot.com/

Any ideas?

toProprietary() takes an API ID as its first argument. Any of the mxn types
that you can create independent of a map don''t have an intrinsic API ID
the
way the main Mapstraction type does. When you add one of these to a map the
map object calls toProprietary() passing in its current API ID; if you call
toProprietary() yourself you need to supply the ID.

The provider code doesn''t show this additional argument - it''s
on the proxy
method of the core type only. The invoker code uses it to pass the call on
to the correct implementation and strips it off the arguments before it gets
there.

Aha! That makes sense and even familiar (I searched the list!) We  
should find some way to make that clearer. Maybe a comment in the  
provider function?

I''m actually in the process of adding a ton of comments, including that
one.
May be able to finish it up and check it in tonight.
