Duplicated URLs - Bug In Page URL System?

[tomgsd]

I'm having a problem with the "Page URL" system added in the 1.9 series.

Using the latest version (1.9.4.2) with pretty URL's enabled, I created a page with the alias "page-1". Next, I created another page with an alias of "page-2" but set the "Page URL" to "page-1".

When I try and visit the first page (with alias "page-1") I see the second page (alias "page-2"). In fact, I can't find any way to access "page-1", even when doing /index.php?page=page-1.

The only way I can get round it is to use the setting "Page URLS are required" (and "Automatically create page URL's" to make things a bit easier) and update all the pages so they have a unique "Page URL".

I think what's missing is a check when saving the page on other pages that don't have a url specified - it looks like it currently only checks the ones where a user has specified a url.

Is anyone else experiencing the same issue?
