Hi Gabor,
I see that you have two mentions of user_ids in the template:
property(outname="user_ids" name="$!user_ids")
property(outname="user_ids" name="$!mesg")
Maybe that's why? I would normally expect just one instance of the same
variable.
My usual way of troubleshooting templates is to write the output to a file
(using the same template). At least this way I would know if the problem is
specific to my destination or to my template.
Best regards,
Radu
