Weird behaviour of +1 buttons
As a title post, I notice then if I add a preference to a post, by clicking the up-arrow button it works as aspected, but if i change my mind and I want to remove my vote, then when i click down-arrow the counter reset to 0 (even if there's some previous votes). Btw, overlapping the mouse-pointer over the counter it show the user(s) name that previously voted for that topic even if the counter shows 0. On the other hand - after having already voted - if I click another time on the button up-arrow (instead of down-arrow) it works correctly, decreasing by one unit and leaving the correct count number of previous votes.
I could see the counter broken somehow.
I accidentally up-vote someone, from 0 to 1. When I tried to fix that it goes -1.
@dLeon Thank for the tip. Yes, there's sure some weird behaviour upon the arrow-vote system
For what I can say, the first button (arrow-up) it's sufficient because if pressed twice, it works as -1 voting. Could be an idea to leave only that button (more clear, mopre space for post and (maybe) less developing works to bug-fix).
Edit: No, sorry... i write a bullsxxt ... forgot about the -1 voting...
@dLeon Well, there might be an innocent purely technical explanation, as you hypothesised... but given the nasty posts in the thread to which i alluded, from a couple of repeat trolls, i cynically assumed that in fact the explanation was that said trolls were downvoting [= invisible userIDs] any upvotes [=visible userIDs] they saw. These idiots are so small-minded.
After all, sadly we already have several precedents in these fora where such trolls have targeted some individuals they didn't like, & massively downvoted them. Sad morons.
Not taking into account any invisible downvoting, there is an easy explanation.
Let's say someone's count is at 0 and you upvote -- the count goes to 1. If you want to take your vote back now and press the downvote button, the count goes to -1, because you just downvoted them. That's how it's supposed to work, and not a bug.
It's a bit counterintuitive, but if you want to remove an upvote you gave someone, you have to press the upvote button again. And if you want to remove a downvote you gave, you have to press the downvote button again. This will remove the upvote or downvote cleanly, without voting into the other direction
(I did it with the OP to check this real quick again)
@luetage thank you and sorry for late reply (i was missing you're reply). Yes, it's pretty clear once you know that. Mumble... I thiunk a new help post comes soon
