That's fine, except that it won't work without also changing code in the 
controller, e.g.
 
 my @objs = $model_class->search_like( .. );
 $c->stash->{one_result} = \@objs;

See the CDBI docs regarding iterators and list vs. scalar context.

If we're addressing Chisel's problem, this is really a CDBI question, in
which case we're getting OT. So I hope this response will close out this
thread.
