TYPO3 Core

In general it is possible in TYPO3 to limit the editor permissions only to edit the page properties and not the page contents - this could be configured by the "access" module and the "Edit page" and "Edit content" permissions, see attached screenshot. Provided that the user und group rights are already previously fully defined.

But since TYPO3 6 or FAL integration the editor needs not only the "Show page" and "Edit page" permission to a specific page, but also the "Edit content" (marked in screenshot) if he wants to edit the "media" field in the page properties. Otherwise the editor can click the "create new relation" button, but if he selects an image a popup warning with "Access denied" occures. Any other field in page properties can be edited and saved by the editor without the permission "Edit content".

It seems to me like a bug with page permission and occurs in TYPO3 6.0, 6.1 and also in 6.2.12
