TYPO3 Core

When creating a new TypoScript template in the backend, TYPO3\\CMS\\Frontend\\Page\\PageRepository->getPage() gets called. This method calls "getPage" hooks, which may be 4.7-compatible extensions that have to implement the t3lib_pageSelect_getPageHook interface.

Currently, the t3lib_pageSelect_getPageHook alias mapping is defined in typo3/sysext/frontend/Migrations/Code/ClassAliasMap.php, which does not get loaded in the backend - only in the frontend.

So when creating a new TypoScript template (not an extension template), the backend crashes:

PHP Fatal error:  Interface 't3lib_pageSelect_getPageHook' not found in cwe/typo3conf/ext/contexts/Classes/Service/Page.php on line 41

You can reproduce this issue with TYPO3 6.2beta3 and an installed "contexts" extension.
