[TYPO3-mvc] Strange behaviour when update($object) - not all attributes was written to the database.

this is a known bug. The check for changed properties currently fails if 
the changed object itself wasn't modified. So replacing a "clean" object 
with another "clean" object is failing. But there's a patch available 
with the request to test it in order to get it in extbase 1.3.0 which 
will be shipped with Typo3 4.5. Please have a look at the topic "RFT 
(Request for tests): 1:n mapping is never updated" from 3 days ago by 
Bastian Waidelich.
