TYPO3 Core

A redactor copies a page in pagetree via context-menu.

He inserts the same via context-menu into a page where he has no rights to insert it. Now, the following happens:
1. The menu for inserting the page is shown, even if the permissions are not there.
2. After the insertion you can read for a few seconds the following message:

Exception

[1.1.12]: Attempt to insert a record on page '%s' (%s) from table '%s' without permissions. Or non-existing page.

3. The page is inserted into the pagetree at the place selected as if the permissions were correct, but the page has the id of the original page. Any changes in this page affect the original.
4. After logout and relogin the copied page is no longer in the pagetree. Only the (changed) original is available.
