yah, normally they get mapped as constraints ... let's see

good start ;)

looks good. does the database have a field "members"? if yes, please 
post TCA-config, if not, please post mapping-TS.

not sure about that, but you might simply skip that. you need this, if 
you want to work with an empty objectStorage, but as you just use it in 
a property, the datamapper will build an objectStorage (filled with 
items or empty) for you anyway.

And you've got a set(), aight?

It takes the type-hint (the part in <>), tries to get that model and 
then fetches the objects. if this is not in-depth enough, please let me 
know, I'll explain a little bit deeper if this is of interest*. ;-)

you don't have to, the way you are going is perfectly ok. I do it the 
same way with categories of an image ...

you forgot to tell us, what exactly is your problem. ;-) don't you get 
data at all? an exception?
