I get it know; sorry for being dense.

Problem is:

# og/lib/og/entity.rb

    # farms/rp: is there not another way to access the root class?

    def schema_inheritance_root_class
      klass = self
-      until !Og.manager.manageable?(klass) or
+     until klass.schema_inheritance_root?
        klass = klass.superclass
      return klass

#manageable? was being used to find classes to manage. To prevent Og from
managing already managed classes, I modified it to exclude classes already
managed. Hence the problem. I made this change to accomodate multiple
stores. The way Og worked, it tried to enchant everything it could, even if
it was already managed.

I'm thinking the above change should be fine. It passes your test anyway. ;)

Seriously though, it doesn't appear to change a whole lot:

$ grep -R schema_inheritance_root_class * | grep -v '~' | grep -v def
og/store/sql.rb:    klass = klass.schema_inheritance_root_class if
og/store/sql.rb:    owner_class = owner_class.schema_inheritance_root_class
if owner_class.schema_inheritance_child?
og/store/sql.rb:    target_class =
target_class.schema_inheritance_root_class if
og/store/sql.rb:      klass.const_set 'OGTABLE', table(
og/store/psql.rb:      klass.const_set 'OGSEQ', "#{table(

$ grep -R manageable? * | grep -v '~' | grep -v def
og/manager.rb:    manage(klass.superclass) if manageable?(klass.superclass)
og/manager.rb:      if manageable?(c)
og/entity.rb:      until !Og.manager.manageable?(klass) or

I note you and Rob are listed in the above code, so what do you two think?
I'm new to STI and I've already broken it, so I'll humbly leave it to the
two of you.
