Issue with admin page hierarchy in Menu admin

[hcceast]

Under Appearance > Menus in the left column under Pages, if I have more than 50 pages, the hierarchy view gets messed up. The issue seems to be related to paginate.

If I change the "50" on lines 589 and 809 of wp-admin/includes/nav_menu.php to "955" the hierarchal admin menu works with 50+ pages.

Attached are two XML files. One contains 50 pages and the other contains 53 pages. I've loaded them into fresh installs of 3.2.1 using the twenty eleven theme and no plugins.

Paginate is great if it works right, if it won't work, just increase the number per page to something very high and people can scroll. I'd rather scroll than not have hierarchy work right.

Taxonomies are also affected.

Closed #19837 and #20351 as duplicates.

I suspect the $depth parameter could be failing during pagination.
I'll take a look into it see if I can find anything.

Is anybody working on this? The current release (3.3.2) is still affected.

The version tag is used for when the issue was introduced, not the most recent version it occurs in.

When is this ticket going to be resolved? is there a patch? This is core functionality keeping my project from launching which is over 18months old. not cool. I can put in pages manually but my client cant manage them and as it turns out they have a very deep sitemap to place in the menu's section.

so again.. when is this to be resolved?

@energy0m: the issue will be resolved when... someone takes the time to resolve it. It seems Sergey is looking into it, but if you are in a rush, I suggest you contact him and - here's a crazy idea! - offer him to help. In the meantime, I can only suggest you take a chill pill and read up on what Open Source is all about: ​http://en.wikipedia.org/wiki/Open_source.

How can I help him when I don't know enough about PHP to resolve the problem?

I'm not actually looking into it yet, I've just removed the previous owner so that someone else could take over this ticket. Feel free to submit a patch.

This is essentially a visual bug - the hierarchy is not actually altered, and since nav menus specifically do not rely on the page hierarchy, nothing is broken beyond the visual. Yes, it is a bug and yes, it is frustrating, but it shouldn't be something that holds up a launch.
