Description Dennisj 2012-12-11 04:03:14 UTC

Hi,
Clicking on the "expand" widgets  [+] on Wikipedia for numerical (number) only categories gives: "Problem loading data. Please wait a moment and try again" error messages. 

To reproduce this problem go to this page, for example...
http://en.wikipedia.org/w/index.php?title=Special:CategoryTree&target=100s
...and click on the "expand" widgets  [+] for all the 100, 101, 102...to 109 categories. This gives "Problem loading data. Please wait a moment and try again" error messages.

Then try for the "100s births‎" category on that page, this will work properly, as expected.

It seems that category names made up of 'numbers only' give this error, but if one or more letters are added to the category name, the error does not show.

thanks.

I can reproduce this on http://en.wikipedia.org/w/index.php?title=Special:CategoryTree&target=100s with Firefox 16.0.2 on Fedora 16.

Expanding does not even trigger any outgoing request, so I guess that the shown  message is kind of fake already.

Comment 3 Michael M. 2013-07-05 10:00:54 UTC

From JS code:

		// Don't make a request if there is no title.
		if ( typeof ctTitle !== 'string' ) {
			error();
			return;
		}

This should be something like "if ( !ctTitle ) {" istead.

I just checked mw 1.22.0 (a private wiki) and this problem sadly still exists :-(

And actually the problem is also present in 1.23wmf8 as you can see here: https://en.wikipedia.org/w/index.php?title=Special:CategoryTree&target=100s
