I've always known that it takes someone from .nl to properly

OK, closer!  Here's the problem.  I have a method that returns an
array of objects.  This works great with dtml-in.  I want to make a
simple tree of these objects, so that when the person clicks on the +
sign, the given object is displayed.  So, I set leaves to be the
object's display method and branches_expr to call the function.  But
-- this gives the object, but clicking + gives another listing of the
same objects, and this keeps on going, presumably infinately.

I tried passing tree-level to the function, but _ mysteriously is
inaccessible inside dtml-tree.  

What exactly should I be doing?

FWIW, I created a product and an Event class that holds information on 
events.  I then made a folder called eventDb that is populated with
these types of objects.  In that folder's parent, there is a
getEventsByDate method, that takes start and end dates, and returns a
list of objects that fall in that range.  I then want to have a nice
tree display of these objects.

Thanks,

John
