[TYPO3-mvc] extbase master and TYPO3 4.6.0alpha1

[Dennis Ahrens]

Hi list,

the current extbase master seems not compatible with TYPO3 4.6.0alpha1. 
i've searched around for an hour now, but i'm not familiar with this topic.

I get this fatal with fresh checkouts:

Call to a member function getCache() on a non-object in 
/home/ahrensde/t3/git/extbase/Classes/Object/Container/ClassInfoCache.php on 
line 89

I've tried to call t3lib_cache::initializeCachingFramework() in the 
constructor of ClassInfoCache.php, but than i get this exception:

#1203699034: A cache with identifier "extbase_object" does not exist.

I had a look at t3lib_cache, but on reading it seemed as if there are 
only FE-Caches available (but i'd like to use extbase in BE).

Do i miss a point here or has anybody a working setup out there?

regards
Dennis
