though i essentially answered this question in my last email, i'll add
some info here for general education:
no, the ViewToolContext doesn't auto-magically create toolboxes. it
only finds them auto-magically. in order to make tools more easily
accessible, the actual Toolboxes are put into the
request/session/servletContext attributes after being created by the
ToolboxFactory. the ViewToolContext just knows how to find them
there.
this is so that apps don't have to use a Context implementation at all
to get access to tools, as some people wanted to use tools outside of
templates. :) it also gives frameworks some extra flexibility if they
want.
