I tried to reproduce this in Zope 2.3 CVS.
I had to replace "_" by "_vars", as "_" gave me
a "NameError: _" (do not know why), but otherwise,
it worked.
I got your error, too, when I tried 'branches_expr="y"',
but that is expected, because in this case, the
expression evaluates to a DTML method and does not
have a "__getitem__" as required by "tree".
