TYPO3 Core

I have set up a custom prototype like this:

TYPO3:
  CMS:
    Form:
      formManager:
        selectablePrototypesConfiguration:
          200:
            __inheritances:
              10: 'TYPO3.CMS.Form.formManager.selectablePrototypesConfiguration.100'
            identifier: 'poweruser'
            label: 'Poweruser'
            newFormTemplates:
              200: null

      prototypes:
        poweruser:
          __inheritances:
            10: TYPO3.CMS.Form.prototypes.standard
          formElementsDefinition:
            AdvancedPassword:
              formEditor: null

Expected behaviour¶

• the form wizard displays a new "Form prototype"
• the "Start template" "Simple contact form is gone"
• within the form editor the form element "AdvancedPassword" is not available anymore

Current behaviour¶

• the form element "AdvancedPassword" is still available
