I noticed that you can't cascade an include more than twice on the
same association (for has_many at least). It seems that the
association name table alias is used as a key to store the number of
times that the association has been used in the include. This allows
the alias to change for each subsequent join. However, the way that
the code was written caused a new key to be used each time the alias
count was incremented. As a result, you could not cascade more than
twice on an association:
Tree.find(:first, :include => {:children => {:children => :children}})
The attached diff fixes this issue and passes all unit tests.
