Hi Art,
Thanks a LOT for these very helpful pointers and for mentioning the
legacy documentation in WO 4.5.
There's a gold mine of information buried there for the more
conceptual aspects of WO which I think one really needs to grasp.

I've searched through all the WO Apple docs (spotlight on Leopard
truly rocks!) to find a good explanation of the use of the caret
"^" character in bindings in custom WOComponent .wod files and
couldn't find any (except in a a couple of EO docs). It's mentioned
in passing in the "WOComponent HTML File Format" reference but not
in the "WOComponent Bundle Format" reference. In the HTML file
format file they also mention prefixing key binding with a ? in
the .wod file but I could not find a detailed explanation for this
either.
The only place I could find documentation about the use of the "^"
was in some of the WO books.
Did I really missed it or such a basic piece of information is
actually missing from the docs?
Carat syntax is discussed at the bottom of the page <http://developer.apple.com/documentation/LegacyTechnologies/WebObjects/WebObjects_4.5/System/Documentation/Developer/WebObjects/DevGuide/ReusableComponents5.html

was written during the WO 4.5 timeframe when WO licenses were being
sold for tens of thousands of dollars (maybe there's a correlation
between license cost and documentation quality).

If you can't find the WO documentation that you need on your
internal disk, search Apple Developer Connection's Reference Library
as well. WO documentation is in the Internet & Web and Tools
categories with past documentation preserved at < http://developer.apple.com/referencelibrary/LegacyTechnologies/
>.
Aloha,
Art
