My apologies. There IS code. I blame the long day and a trip the

Now that I see your code, I understand your problem. I too had the same
problem. I believe it has to do with the fact that the resultset
returned by DBIC is not really anything until it's used, and TT is
guessing wrong about how to use it.

Try adding this to your search:

   .search({ col => $value }, {cache => 1})

and see if that fixes it.
