VisualEditor: Opening the drop-down for a category in the page settings > category pane can cause a category entry to be duplicated
Closed, ResolvedPublic


Fram reports:
<<Having looked a bit more at categories, I encountered another strange phenomenon. On Opel Laubfrosch, which has a lot of categories, the order of the cats on the page settings tab changes. Initially I get 8 categories, from "Opel vehicles" to "compact cars". But when I e.g. click on the drop down button next to 1920s automobiles, and then click again in the "categories" window (to close the drop down without any changes), I get 10 cats instead of 8, and in a different order. "Vehicles introduced in 1924" and "Sedans" are doubled (explaining the increase from 8 to 10), and the 3rd one is now no longer "1920s automobiles" but "1930s automobiles"... This can go on for quite a while, with the occasional disappearance of a cat as well apparently (normally the last one). Things start to break down, with the page settings then no longer working, or it being no longer possible to add a cat, and so on.>>

I can confirm what he says, and this bug does not look browser or skin specific.
VE will let you save in a situation where you have these cats duplicated, and a "saved edit" message will also pop-up, but there will be no trace of the edit in the history. Plain removal of all the categories works fine instead: .

Didn't we fix a bug like this recently? Is this still valid?

Yeah, I think so.

Column Prototype
This is a very early prototype of a persistent column. It is not expected to work yet, and leaving it open will activate other new features which will break things. Press "\" (backslash) on your keyboard to close it now.
