I encountered a funky problem during my first encounter with CatalystX::ListFramework::Builder ... and (just before throwing my hands up and Petitioning my Fellow Monks) ...solved(!) it.   W00t! W00t! :-D

To save your precious hair-follicles... here's what the problem was, and here's how I diagnosed and solved it.

The Problem:

I followed the man-page instructions most carefully, to create a DBIx::Class::Schema for my new database and to reference it properly within the configuration file. So, when I started Catalyst and entered the /admin page, I found the complete list of tables (yay!) ... but upon selecting any of those tables, I was taken to an edit screen that was ... empty. (boo hoo!)

Well, certainly not completely empty ... it had the header, the breadcrumbs bar, and the footer. But it had no table in-between. The same was consistently true for all table screens. An obviously-sensible page (and page-source...), but no table.

The Catalyst output showed nothing useful.

The Clue:

As we all know, “Firebug is a wonderful thing.” This JavaScript debugger gave me only one slim clue in the console output: “file not found.” There were no “404”s anywhere to be found.

The Solution! :

Upon very close re-inspection of the Catalyst output, I noticed that the various requests for JavaScript components looked like this: static/js/extjs/extjs-2/blah... Now mind you, the Catalyst log did not say anything further. It did not say that either the files or the path did not, in fact, exist...

But in fact, they didn't. The correct path (I had typo'd it in the configuration) should have simply been /static/js/extjs-2. No files existed at the path that was originally being used.

In closing...

I am genuinely surprised to discover that, when Catalyst is asked to serve-up a static file that does not exist, it says nothing in its log file. I am also somewhat surprised to notice that a web-browser kept equally “mum.” The upshot was, at least for me, a problem that was trivial to fix, but quite difficult to spot.

So... “now you know” and “hope it helps.” May the next hair-follicles to be preserved be your own! (They certainly were not mine.)   ;-D
