Not quite, since this was about principal annotations and principals 
cannot be found by object traversal. It was specifically about letting 
the adapter know the context, not about finding a different adapter 
based on context.

In general, using "context=a" should give the same result as 

In the particular case of principalannotations, this would not help. 
There the adapter is the same globally, but needs to know the context so 
it can find the proper utility to use. To make it work you'd need to 
register a different adapter for each utility. This is certainly doable, 
but probably not worth the effort.

Hope this helps
