Did so - but no clues this time.

This is mod_perl 1.25.

I=27ll remember that one.

Anyway, my problem is solved - due to a weird problem, my =24UserName
variable got the wrong value in some situations.

Accordingly, I got an anonymous login instead of an authorized - and
the query didn=27t return any results.

So the function =24result->entry(0)->get_value() didn=27t exist, and the
script halted; quite fair.

What I don=27t understand now is that I tried the following construct:

if (=24result->entry(0)) =7B
  =40ACL =3D =40=7B=24result->entry(0)->get_value(=27ACL=27, asref=3D>1)=7D=
;
=7D

That test proves positive even though entry(0) doesn=27t exist - and it
tries to execute my code. How come?

Thanks for your interest so far.

Regards,
Lars
