We have a Phriction page /w/a/ with lots of sub-pages (/w/a/1/, /w/a/2/, etc).
I used Actions -> Move Document to move this to /w/b/. The page, and all its sub-pages, were moved.
On /w/a/, I see:
> This document has been moved to /w/b/. You can edit it to put new content here, or use history to revert to an earlier version.
On /w/b/, I see:
> This document was moved from /w/a/.
Now, here's the catch: let's say I want to undo this move. I can't find a way to do so. Here's what I tried:
* Go to /w/b/, use Actions -> Move Document, type in /w/a/ as the destination. I see an error:
> Unhandled Exception ("RuntimeException")
> Undefined variable: message
(This error only seems to happen when I use /w/a/ as a destination. I can move to other places, like /w/c/, just fine.) I feel like "deleting" /w/a/ might fix this, but I can't find a way to do so.
* The instructions (quoted above) said I could "use history to revert to an earlier version." /w/b/ has no earlier versions. /w/a/ does have earlier versions, and I can view them, but I see no way to revert to one.
