I still think, the requirement itself is probably screwed.

Such screwed requirements just happen, and if they happen, then a
screwed implementation may seem like the correct answer - until
something harmless happens, that crashes and burns the screwed
solution and leaves you in the void searching for an alternative
screwed solution that survives at least until next time...

Back to the Box-example: as the Box-framework may not expect the
getContent() call to depend on any outer local context, it might
evaluate it earlier, and just return a cached result on your call.
This of course will crash and burn your approach, as you built on
the unfounded assumption that each Box's getFieldContent() wouldn't
be called beforehand.  If the Box-framework really gave such a promise,
then it had better provide a context parameter already, lest it be
screwed itself.
