All,

I hear tell that neither Streamlined nor ActiveScaffold support the use  
of has\_many :through relationships in the sense that HM:T relationships  
will effectively be read-only in those frameworks.

Does anyone know why this is? I assume that it has something to do with  
the way that the relationships are introspected on?

Thanks,  
Wes

ActiveScaffold supports R/W has\_many :through. Dunno about Streamlined.
