I edited an answer and suggested a small change that was greatly improving the post. This suggestion got rejected. When I looked into the revision history I noticed a strange behavior.

The edit I suggested was made under someone else's username - apparently the one who reviewed and improved my suggestion. So far everything seems fine: (Revision link)

But then I looked into my suggested edit itself to see what happened to it and saw this:

enter image description here

Of course the difference here is too minor to be approved. But what is displayed here was not my suggestion! (That suggestion can be seen in the revision 2 in the image above)

So what happened here? Was this due some strange timing issued in improving and approving my suggestion without marking it as helpful?

Your edit suggestion was made after someone else had made most of the same edit. Revision number 2 clocked in at 10:00:24, and your suggested edit was recorded at 10:00:35.

The system only recorded the difference between the second edit and yours, and that difference amounted to a minor edit.

A case of bad luck, I'm afraid!

Interesting - as I saw this line in the edit box when starting to edit: try (byte[]) getValue(key).getBytes(); so in this rare case there seem to have two people seemed to have clicked on "edit" at the same time... Thanks for clarifying nonetheless. – Spontifixus Nov 8 '12 at 10:42
@Spontifixus: There is no notification to show someone else is editing the post already, and it is impossible to tell who started to edit first. All I know is that you started your edit before the other editor had submitted his changes. – Martijn Pieters Nov 8 '12 at 10:44
The link to the edit page normally gets disabled if another user is editing that post. There are several circumstances however where this mechanism does not come into effect: One of the users has had loaded the page already or both clicked at the same time... Conclusion: As you said: A timing issue and a case of bad luck ;) – Spontifixus Nov 8 '12 at 10:47
@MartijnPieters actually there is a message after somebody else finish to edit the same post, something like "this post has been edited, your edit will be submitted only if [can't remember more]" – Shadow Wizard Nov 8 '12 at 14:55
