[TYPO3-mvc] Problems with updating / mapping, related issue #9270

[Michael Knoll]

Hey Franz,

thanks you very much for your reliable answers on this list :-) 
Unfortunately, in this case your tip did nod lead to a solution... I 
already have the @lazy annotation for my album on the Item model... the 
problems still occur...

I ask myself the question, whether I am doing something wrong or whether 
this is a bug in Extbase. The methods used for mapping the data on the 
model are rather confusing to read so it is not that easy to figure out, 
whether they are not doing what they should my model has a mistake. 
Still I think that this usecase is a rather simple one and it should 
work without any problems... I'm willing to help you out on fixing this, 
if it is a bug but I don't know how to find out, whether it is one...

It would be really nice, if any of you could give me a hand on this!


Greetings

Michael
