[Zope-CMF] Debugging TAL?

[J C Lawrence]

How do you debug TAL errors?

I recently updated a bunch of bits on my test box (CMF, Plone, CMFTypes,
the various CMF Collective bits, etc), and am now getting KeyErrors on
"tabindex" every time I try and create a type derived from CMFTypes
(well, I think that's the pattern).

I can't tell where it is coming from -- the error page doesn't have a
tracedump, and the number of references to "tabindex" in the TAL code is
__large__.
