Matt: "So it works on the first request but not on the second?"

Yes, it works on the first request and not on second. But, after
changing it to this: $data = $c->model('Ttrack::Ttrack')->search();
it's working fine, although any more suggestions are welcome.

No, don't do that.

Those two lines are exactly equivalent except that ->search will cause
a completely pointless clone of the resultset.

$c->model('Ttrack::Ttrack') is -already- a resultset for the whole

That's why there's something in there to search on.
