this is a duplicate of a couple of other issues. so far the only resolution has been to advise everyone to turn off moderation.

looks like a duplicate of #760.

What version did you use?


ojii commented Aug 14, 2011

is this is the only solution? "this is a duplicate of a couple of other issues. so far the only resolution has been to advise everyone to turn off moderation."

i've also had this same problem and that's the best solution i've been given. i'm not saying i'm happy about it but if you want to avoid that problem then so far that's the best way known to avoid it.

@simul14: Your specific issue might be fixed in 2.2

The main reason there's no better solution for this is that we do not currently have a real way to programatically reproduce the issue, which makes it next to impossible for us to write a fix, since we couldn't tell if the fix worked. That's the reason why there is a bounty of 150USD on #760, which is mostly for providing a unittest that reproduces the issue and shows that it's fixed or not fixed.

While this is a bigger issue, the fact that we don't know how to tell if it's fixed or not forces me to not mark it as a blocker, in order to allow the CMS to move forward.
