No page cloning if page has children (as a non-superuser)

[Lenz]

Hello all,

i have a problem with page cloning, namely if i want to clone a page together with children pages (page-clone-tree) as a non superuser:

Page cloning is a important requirement coming from the future editors of the website.

reproduction of my problem:
1. login in processwire admin backend as user with the custom role editor

2. switch to Pages -> Tree View
3. click within the tree on the page which i want to clone

4. click on button copy next to the page  (page has children)
5. result:

=====================================================================================

page cloning doesn't work, instead reload of complete pages Tree and Message on top: "You are logged in".

=====================================================================================

if a page has no children, the page cloning works.

Also as superuser page cloning is functional.

My system is processwire 3.0.12 multilingual

the template of the parent of the page, which i want to clone has the following configuration for role editor:

Tab ACCESS:

VIEW PAGES
ADD CHILDREN

 (makes no difference if i also add all other permissions like EDIT and CREATE PAGES, but the role editor shouldn't be allowed to create and edit pages on this level)
    
Tab Family:

May pages using this template have children ?  -> YES
Can this template be used for new pages? -> YES

the template of the page, which i want to clone as editor has the following configuration for role editor:

Tab Access:

VIEW PAGES
EDIT PAGES
CREATE PAGES
ADD CHILDREN

Add permissions by role:

editor: page-clone
editor: page-clone-tree
editor: page-delete

Tab Family:

May pages using this template have children ?  -> YES
Can this template be used for new pages? -> YES
Allowed templates for children -> [child-template]

the template of a child of the page, which i want to clone has the following configuration for role editor:

Tab Access:

VIEW PAGES
EDIT PAGES
CREATE PAGES

Add permissions by role:

editor: page-clone
editor: page-clone-tree (doesn't make sense here, but makes no difference whether this is activated or not)
editor: page-delete

Tab Family:

May pages using this template have children ?  -> No
Can this template be used for new pages? -> YES

Have i overseen something or is there somewhere perhaps a bug?

Thank you very much in advance.

meanwhile i have found out, that if i set the cloning permission directly at role level (Access -> Role -> editor) and disable the cloning permission on template access level, the page tree cloning works, but now the cloning functionality is assigned to all editable templates.

I think for now i can llive with that, although i'd be happier if i would have been able to configure cloning per template...
