This can more concisely be written as <dtml-var "table_of_type(target, _, type_list = ['FooType'])">. Specifying the client like this is a little-appreciated compensation for having to make the first two arguments explicit when passing keyword arguments.
Ahh, cool! I was getting ready to go dig into the code and see what kind of flexibility I could get from that first argument, but you saved me the time. Thanks!
This can also be used to get around acquisition problems. Suppose you don't want to clutter up your root folder with this sort of factored method, so you stick them all in a folder called '/lib'. Now you want to call '/lib/table_of_type' on folder 'target'. If you try...
<dtml-with target><dtml-with lib><dtml-var ...></...></...>
..you'll get a list of object in 'lib' instead of 'target'. Reverse the 'dtml-with's and it may work, but it's awkward, and fails if there is a '/lib/target'. On the other hand...
<dtml-var "lib.table_of_type(target, _, type_list='Folder')">
..will work just fine (even if table_of_type is a Document instead of a Method!).
This makes perfect sense, and is going to save me a lot of headache on the project I'm working on. Woohoo! :)

P.S. I *really* like this Zope Guru of the Week idea. This could turn into a real Zope knowledge base.
I agree! Kudos to Tres and anyone else involved. And thanks to Evan for the pointers on my submission. --Jeff PS. If I can get the formatting right, next time... :) --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff@goingv.com Going Virtual, L.L.C. http://www.goingv.com/
