i believe this is a bug,

Having the same issue -http://www.concrete5.org/community/forums/usage/pages-with-pending-... - I thought I posted a message on the bug tracker a while back, but I don't see it any longer.

hmm its possible that if no approved version of the page has been made yet that it wont show up in a page list - i can actually see that as more of a behavior than a bug, but i'm not sure if it is really the case or not.

there's also a setting in the page list that determines if it should show all page links regardless of a permissions check first, or if it should only show pages the current user has access to - that's worth playing with.

also the last line in your post confuses me... "currently older versions of the page.." you're saying a page has been made, it has an approved version, and as soon as a new version is made it no longer is listed in the page list? That would certainly be a bug but i don't think its the case.

Franz, remember when i left the moving a site page in editmode, it had previous versions, but since it was in editmode it wouldn't display
