.... DMTL method "y": OK, this works:

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".
