[TYPO3-mvc] Mapping various Objects to a Domain Model

[Henjo Hoeksma]

HI Thomas,

aren't you just trying to add objects to the server object? If it is
attached the value is true, if not it isn't?

My usual way on building a model is to start with the ideal model situation
but then slim it down as much as possible to make it functional and as
uncomplicated as possible.

I hope this helps.

Kind regards,

Henjo
