TYPO3 Core

The documentation states that pre TYPO3 10.4, pages that were supposed to be used as frontend pages, needed to have a doktype below 200. Since 10.4 this restriction would no longer apply:

• https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/PageTypes/Introduction.html

In 10.4.17 custom page types with a doktype higher than 200 (I tried 301 and 302) do actually render in the frontend. Some things do not work though:

• Page Type Shortcut:
  A shortcut to a page with a doktype > 200 does not work in Shortcut Mode First subpage of selected/current page. Subpages of the current page with a doktype > 200 will not be considered and thus not called in the frontend, even if they clearly are the first subpage of the shortcut.

• Link Browser
  Pages with doktypes > 200 will be muted in the page tree, just as Sysfolders. Thus you cannot set links to pages with doktype > 200 or content elements on these pages.

• View button in doceader
  When editing a content element on a page with doktype > 200 the view button will not render this page in the frontent. In my case it rendered the root page instead with doktype = 4

I eventually changed my custom PAGES_TYPES to a number below 200 and the described problems disappeared.
