[Grok-dev] Problem with z3c.autoinclude of eggs in the Products namespace

Hey Vincent,

I don't know much about buildout or the inner workings of Five, so this is a
bit of a stab in the dark, but it sounds to me like package inclusion order
is the most likely culprit here.  As a quick sanity check, could you try
including the package directly, and see whether the problem remains the
same?  In src/myproject.policy/myproject/policy/configure.zcml, just change

<includeDependencies package="." />


<include package="Products.mypolicy" />

If my guess is correct that package inclusion order is somehow the cause,
then this shouldn't change any of the symptoms you're seeing.  That'll at
least be useful information to start debugging the problem.

Actually, though, do you need to explicitly include Products.mypolicy's ZCML
(whether directly or indirectly through z3c.autoinclude) at all?  Shouldn't
the <five:loadProducts /> directive in your site.zcml load
Products.mypolicy's ZCML files for you, before myproject.policy's ZCML is
even loaded?
