I agree and Im just agreeing with what Chris said but putting it in a
different way.

His main arguement here seem to be that building complicated stuff in DTML
sucks. He's right it does, but you shouldn't be building big complicated
stuff in DTML (as Chris says).

We almost exclusively write our code in python which means:
-    you can grep it
-    you can use CVS
-    you can write any test suite you like

For most small applications DTML can suffice, but when it gets large you
should separate your code the way its intended, DTML is for simple logic and
presentation ONLY. Whilst PythonMethods are cool, I would naturally stray
away from them for the above reasons for anything longer than about 5 lines.

The heavy lifting, logic and anything more should be in python. I won't
pretend its particularly easy Zope hurt quite a lot some times, but we got

We actually tried cataloging the dtml... and it didnt work. This can be a
pain I agree.

You can write a your own test suite and for most web applications thats what
people do.

Hear, hear. As above, the "" is useful though...

To me you should "never" make the assumptions you suggest regardless of the

"Apache already exists and is highly flexible and configurable" of course it
is, use it if you want, grrr..... TMTOWTODI.

More comments I would like to argue with:

"it's not apparent that DC is quickly responding to fixes."

I think DC and this group are great at responding to fixes, especially
anything serious or security related. Ok there are still a few bugs out
there that havent quite gone yet, but everybody has been great. The good
community spirit for me is one of Zope's strengths.

"Object traversal is complicated since objects can affect how they're

And again this is bad for what reason. More power to us I say.

Thats it.
