When using the feature "add album" or any other type of page to an existing page becoming de facto parent page, we get immediately to the new editor, with the future page already being attached. When skipping to the old editor, which I continue to use for a multitude of reasons and which should in my opinion be called simply "HTML editor", the future page is not considered anymore as an attachment and is attached to nothing.
Example :
I am here :
http://www.summitpost.org/western-tatra ... nie/185284
Add album :
http://www.summitpost.org/new_create_ob ... n=19.84130
I click on the old editor and I get :
http://www.summitpost.org/create_object.php
while the correct next URL should be :
http://www.summitpost.org/create_object ... n=19.84130

Same bug when adding images with the new editor despite using the old or new editor for images does not have so much significance.
