Try changing "% if len(c.paginator):" to "% if True:". If that works,
the problem is that the underlying iterable does not have a length. I
would expect an AttributeError in that case, but it's possible the
error is being suppressed for some reason.
Also, check "view source" in your browser. It's possible that it's
outputting empty HTML tags, which are invisible.
If that doesn't work, tomorrow I can check my work application to see
how I handled it. There should also be a paginator attribute for the
record count, which is the same as what the length would be.
