TYPO3 Core

As an editor, I want to be able, to edit / view two or more forms parallel.

Often like to copy settings from one form to another. This is not possible at the moment.

This ends in an error:

Oops, an error occurred!
Exception while property mapping at property path "": Unauthorized modification of "prototype name" or "identifier".
More information regarding this error might be available online.

Applies to TYPO3 9 and 10.

• Editor is able to view / edit more than one form
