Item14765: Empty headings make section editing button edit the wrong section

If a topic contains an empty heading, e.g.

---++

or

---+!!

then in all subsequent sections, the "edit section" buttons (which become visible on mouseover) will not edit their own section but the previous section.

Two empty headings make the buttons edit the pre-previous section. And so on (tested until level 5).

However: Two directly consecutive empty headings with no space in between,e.g.

---++
---++

(as opposed to

---++

---++

)

increase the offset only by one, not by two.

Edit: I was wrong in the first place: If the heading contains whitespace, the problem does not appear! I only appears with empty headings.

My first reaction would be: why are there any empty headings...? Seems to be wrong in the first place.

Could you indicate which plugin this is that you are using? Thanks.

Thanks for your quick response!

Well, in our medium-sized company's wiki, I found hundreds of these. Seems there's more than one user doing it wrong ...
Maybe a lot of these empty headings come from people using templates.

EditChapterPlugin (I've now inserted that into the form at the top of this page.)

Maybe appending a ? to the regular expression part ([^\+#!].+?) in line 205 inside sub commonTagsHandler of Core.pm or to the (.+?) in line 400 might be part of the solution.

This is only an (long-time-since-)educated guess; I haven't programmed in Perl for ten years and I wasn't a great Perl programmer before that, so I don't really understand the whole module. => Someone else should check if my assumption/proposal is right.

Does it solve the problem on your install?

I'm so sorry, I forgot to answer! No, it didn't help.
