TYPO3 Core

Given I have a Backend User who is
- allowed to see the Forms module
- is allowed to create and edit content elements of type "Form"
- not allowed to access the forms with the File Storage

When I open the Forms Module, I get a list of forms. I see forms within extensions (if configured so) and I don't see the forms in the File Storage.

When I open a page in the Page Module containing a form that is not stored in the File Storage, I will see Page Module and the content element.

When I create a new content element "Form" I will only see the Form Definitions which are not stored in the File Storage.

When I open a page in the Page Module containing a form stored in the File Storage, the Page Module breaks with the following exception.

#1471630578: No read access to file "1:/forms/globalContactForm.yaml".
