[rt-users] RT 3.4.4 Links Error

Fri May 26 20:48:13 EDT 2006

Torsten, I've uploaded Shredder-0.04 that has fix for this bug. Really
in your description step 3) should be omited as RT doesn't show links
to deleted tickets and do it very deep in the core and shredder was
biten by this. So in result you had a ticket with a link to an object
that doesn't exist.

My solution was to restore the deleted ticket using the dumpfile created by rtx-shredder's --sqldump switch, and set its status to "rejected" so that it isn't automatically purged by our nightly rtx-shredder job.

I didn't try this because I'd rather add unnecessary data than delete anything), or if this is a bug or an unavoidable consequence of using RTx::Shredder to purge our database of spam (there is plenty). The bottom line, for us, was that the two tickets should've been merged, as they were both from a legitimate customer. Deleting one was the incorrect solution.
